Your description of the problem is usually related to graphics settings as the primary cause but can be various things from old or corrupted GPU drivers, old overheating GPUs and other apps causing conflicts. The error reported refers to DiretX which is all graphics related…
The opening of stash etc in the current patch of the game all cause an obvious increase in GPU usage (just watch it using a GPU monitor) that can easily max out the GPU especially if its running at higher resolutions, higher settings or is simply is an older GPU. This can and does cause instability - i.e. crashes - for some especially if there is an underlying issue already. Its like putting your foot down in an old jalopy and it backfires…
A few things while you find the files… :
Make sure that you verify the game files via Steam. Very important as sometimes Steam doesnt seem to install properly - especially after patches… Lots of problems are solved by this so its important to get used to running this verification relatively often - especially if you are having problems.
Make sure that your OS is patched and that you are running a recent graphics card driver… Doesnt have to be the latest as these can be a little unstable (e.g. dont use nvidias 466.77 if you have their GPUs), but something from the last few months. If you are already using the latest driver, then consider rolling back to something from a month ago.
The graphics instability is best tested with the following setting 1080p, 60fps framerate limited (not vsync) and all in-game settings to very low or disabled. If the problem goes away at these exact settings then its a known issue that just needs conservative graphic settings as a temporary workaround.
Make sure to disable any overlays (like steam or nvidia) and temporarily do not use or disable any apps that might be running in background. Note, even if they seem irrelevant, just dont run them while you are testing.
