Crash/Forced restart during loading screen in POE2 (Partial solution)

(MY CASE, I play on STEAM and Windows)

I had a bug a long time ago from POE 1 and now POE 2 that makes (very occasionally) my computer crash and restart during a loading. (never found the problem)

(TODAY)

Recently in POE 2 I had a random crash during a boss fight (that nearly never happened).

After that crash, I crashed several times after during the same hour, so i tried differents settings and update everything. It was horrible at the point that I can't log my characters because the very first loading crashed systematically.

Nothing work and I saw that lot of people had the same issue.

(THE FIX THAT WORKS FOR ME)
After some search I found that the problem is Client Side and came from Shaders.
So I go in the local files of POE 2 (you can go there with "%AppData%" for steam users, a moderator thread explain this for other supports) and there were 3 folders with Shaders (ShaderCache"RendererName") :
- one for DirectX12 (the one i used the most)
- one for DirectX11
- one for Vulcan
I deleted the Vulcan and X11 folders and put my game in X12 and launch the game.
The loads were goods and fix the big problem even if probably i will still occasionnaly crash like in POE 1 but now i can play POE 2 without having 10 PC restarts per hour.
In another thread i saw that when you change your Renderer in POE 2, it doesn't automatically swap the source folder of the Shaders, so maybe your Renderer is using Shaders from another Renderer and might cause the issue. (I am probably cluless but this is the feeling)

Thanks for reading, hope it will work for you.
