I found this on a google search. Since you can’t even get in the game to begin with I doubt it will help, but maybe mess with some of the ini graphic settings?
steamapps\common\Conan Exiles\ConanSandbox\Saved\Config\WindowsNoEditor -> GameUserSettings.ini
Another idea, (this worked for me in Jurassic World Evolution when I was having an unplayable game issue and couldn’t even navigate in the menus), is to tell Nvidia Experience to auto adjust the graphics.
This thread somebody made a suggestion that it could be a RAM timing overclock issue. I doubt your RAM is overclocked on a laptop, but maybe?
This thread that isn’t even Conan Exiles suggests it could be a heating issue? Another I doubt it since you are just trying to fire up the game, it shouldn’t heat up in half a second to the point of crashing.
This thread suggests trying to clock down your GPU slightly. If you are unaware how to do this, MSI Afterburner and some googling should do the trick. This much older thread also suggests people were having issues when their GPU was overclocked.
Obviously, if you can’t tell, I am throwing crap at the wall to see if anything sticks. The slightly good news? Those are just a small handful of threads I found with a quick google search of “[File:C:\UE4\CSAND\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Util.cpp] [Line: 232]”.
I was finding that error on all sorts of threads, some with UE4 engine editor itself, others random like Tekken 7, etc. So mmaaaaybeee, the fix you are in search for could be found off the net this way.
