Game crashes with UnityPlayer.dll error

The drivers are up to date.

I have almost identical components and it seems to have found a solution for me. I turned off XMP in the BIOS. Not a single crash for 3 hours, before that every 10-20 minutes. I’ll continue to test whether it remains stable, maybe it will help someone in the meantime.

Well it seems that changing the RAM file size worked:
11:40 - 15:40 working fine, 0 crashes.
I changed graphics from med to ultra and changed fps max to 120 (i7 12700, 48gb RAM, Nvidia 4060…) and after ~30 mins it crashed again.
I changed graphs again from Ultra to Mid and limited fps to 60
16:10 - 02:30 Working fine, 0 crashes.
However i gotta say that even with graphics in mid it was crashing me whole time till i changed RAM file size, so i guess is a mix of lowering graphics and changing RAM file size. I hope that this fix works for you guys, i really hope cuz is a really weird problem hard to solve.

Edit: Now i remember i just got new Nvidia drivers and some last epoch patch in steam, so… Who knows!

For me nothing seems to work. I have tried everything. Sometimes i can play for hours without crash and sometimes it crashes ever 30min or so. This error is so old yet its still here.

After 6 hours without a single crash, I wanted to test it again and turned XMP back on in the BIOS. So I had the first Unity crash again after 10 minutes. So off again and since then no crash. I have no idea why Unity and LE have a problem with this, but everything works fine for me.

Game still crashes on my end but what helps is decreasing and increasing the paging file. had constant crashes today but after I increased from 8GB to 12GB it stopped. I have 32 GB ram but still need to do this for some reason :confused:

Had the same problem after patch 1.0, this is definitely a problem related to how the game handles system memory management and not a hardware problem. The game ran flawlessly without a single crash for 50+ hours prior to 1.0, but somehow now has significantly higher memory usage.

Checking the log files: Player.log or Player-prev.log (C:\Users"your user profile name here"\AppData\LocalLow\Eleventh Hour Games\Last Epoch or C:\Windows\Temp\Eleventh Hour Games\Last Epoch\Crashes) each log file is filled with the game trying to reference non-existing objects: System.NullReferenceException: Object reference not set to an instance of an object. And the stack trace (end of file) with multiple invalid address calls: SymGetSymFromAddr64, GetLastError: ‘Attempt to access invalid address.’ (Address: 00007FF9D34F0B31)
0x00007FF9D34F0B31 (UnityPlayer) (function-name not available)

This UnityPlayer or Unity 2019.4.40.50731 error is caused by how the game code instructs the Unity engine to allocate and unload memory. The game seems to require much more memory, and specifically virtual memory, after release.
I would encourage EHG to take a close look at their memory management functions throughout and make sure memory usage is at a reasonable level.

The solution was to increase the size of Windows (Windows 10) Virtual Memory page file to: 16384 MB (16 GB) for both Initial size and Maximum size (Custom size).

For Windows 10 (Windows 11 should be very similar or Google: Windows 11 + virtual memory settings)
Click: Start (Windows icon, all the way left on the taskbar) → write: perf and (enter) click “Adjust the appearance performance of Windows” → Advanced Tab → Change in the Virtual Memory box → Adjust the size numbers and click OK → Reboot the system (just to be sure).

Not a single crash to desktop after allocating more virtual memory.
Thanks to Sotoh for pointing me in the right direction a few days ago.

My Graphics Settings: MASTER QUALITY = Low, setting the overall texture quality, which with higher quality generally equals more memory usage. If using a higher setting and still getting crashes, try to increase the virtual memory settings even further: 32768 MB (32GB) etc., and / Or lower the Shadows settings.

Same crashing issue.

Laptop Alienware M15 R7
RTX3080ti
12th Gen Intel(R) Core ™ i7-12700H
32Gb Ram
Driver’s and OS up to date.

Can’t understand why we keep crashing. It’s frustrating to play with such low graphics.

Any news about this issue?

My laptop has 32GB of RAM. If I were to follow your suggestion to increase the virtual memory, should I increase it to 64GB?

The situation is frustrating. Some specific monoliths are simply unplayable.

Ive been in the same boat as everyone else in this thread. I disabled XMP and I havent had a crash at all since. I would really love to not disable XMP, for obvious reasons, so a future fix for this would be really appreciated.

I’m not in the mood to disable mine just because some other players report that they keep crashing after it. Please, if you crash again or if you manage to fix it, repost here :wink:

It is difficult to say how much virtual memory is required, as system specs differ. So getting to a resolution will probably take some tinkering and testing with different virtual memory and graphics settings. The first goal is just to get stability, then you can adjust to higher quality graphics settings, one setting at a time, till the game starts crashing again, and you know you hit the limit.

My suggestion would be to start testing with the following settings:

  • Set your virtual memory to 32768 (32GB).

Graphics Settings:

  • Master Quality = Medium (go to low if crash. This setting resets all the other settings, so adjust afterward).

  • Shadow Quality = Very Low (set higher later with testing, not really noticeable above Medium).

  • Grass Density = Off (Can enable with testing if needed).

  • Reflections = Low (Not much difference going higher later).

  • Ambient Occlusion = Low (Not much difference going higher later)

  • Volumetric Lightning, Screen Space Reflections, Terrain Quality = Very Low (barely noticeable with higher settings)

64 GB virtual memory seems very excessive. But it is very quick to test with your current settings and might just work out.

I dont know if anyone else is getting this. Today I am experiencing way more crashes for some reason. With the XMP disabled and everything low. yesterday i had a few crashes like less than 5 in 5 hour game time. I now get every 5 mins a crash, tried for the last 2 hours. I am really gonna give up on this game if this doesnt get address by devs or at least a proper work around… Since this is a memory leak after all.

Just an update - I discovered my bios had an update (built the system 5 weeks ago) - so installed that and re-enabled XMP. Im 3 hours deep with no crashes at all. Pre bios update that was impossible as my crashes were every 5-20 minutes.

Thanks for the suggestion SOTOH. Updated BIOS to latest version game still crashes, if i set settings to ultra game crashes within 2 mins. get like 150 -210 frames. just makes me so sad…

I have no idea, played POE for 3 hours no issue, juicing red maps with 6k wisps no issues… I am out of ideas, thanks for all the contributions, will try a clean install once more and if that doesnt work tomorrow time to uninstall till next cycle…

Having the same issue. Update BIOS , XMP is disabled, tried varied virtual memory settings, reinstalled the game, updated drivers, compatibility modes, different/low graphic settings and FPS limits… and many other potential fixes. I think I’ve tried everything anyone has suggested on any possible forum or video this week.

I keep crashing constantly… before 1.0 the game was runnig just fine.
I started running the game on Verry Low setting and windowed mode in lower res, while keeping an eye on the Task-Manager. an a random Bridge my GPU shoots up frpm 30% usage to 99% and starts overheating.

unityplayer.dll crashing here as well, wish they had options to turn off settings rather than just very low.
