Hey there, Welcome to the forums…
My guess would probably be that the game crashes have either been due to some sort of file corruption or have caused some sort of file corruption that they cannot now recover from.
First thing I would suggest is that you use Steams Verify Game Files option to make sure that your install is actually still ok.
Next, I cannot get a full picture of your system setup from the info so I dont know what else could be affecting the game… The player.logs you provided are simply truncated before the game actually starts so its impossible to see what is happening beyond that point.
A dxdiag report with diagnostics may provide more info as to what is happening.
From the player.log & your le_graphicsmanager file, I can see that you are running 1080p on a 2070 with all quality on Very Low… This is usually a very stable configuration irrespective of hardware - the only thing I can see that may be causing a potential stability problem is the vsync option - I dont kow what Hz screen you are using, but if its something like a 165hz monitor, that may not be limiting LE - it tends to get very unstable if its not restricted in some way - even on lower settings like you are using… I have also found that even on lower Hz monitors, actually enabling the framerate limit in game, seems to give more stablility than using vsync… I would recommend manually setting this to 60fps limit in game to see if it improves stability.
Other potential issues could be Windows patching, GPU driver versions or even any other applications running at the same time as you are trying to test LE… this includes things like graphical overlays (even Steam Overlay - disable it).
