STEAM DECK issue

I left my steam dec on over night, the game session i was playing hard crashed when I tried to continue in the morning. Did not seem like a problem because I believed at the time that the game haf just timed out.

Upon trying to reload the game it hard crash the moment I hit play via steam.

I Have reinstall, factory reset my steam deck and tried launch option and the game still hard crashes on start.

When I look at the logs relevant information say:

[INFO Client 308] Init SwapChain= 1280x800


[CRIT Client 308] unsupported backbuffer image count

I am at a lost for why the game won't work at this point. I have reinstall, tired the stand alone Client, as well installing on different drives (SD card) nothing seems to work. I know it works on steam deck becuase until 2 days ago it ran perfectly fine.


Any help would be appreciated thank you
