hey dudes, you may or may not remember me but some time ago i posted a thread and i was replied with "Try using ddu to remove the drivers and reinstall them. That card shouldn’t have any issues."
So basicaly i know pretty well my pc but i think some time ago i made some changes to my pc and now Cemu keeps crashing on startup.
So I tried your technique: to use ddu to remove the drivers and install the newest one, the 18.1.2, but either i did it incorrectly or there is another problem so i am asking you for help man.
So i havent changed my specs they are still the same : Intel Pentium G4600, 8G Ram DDR5, Radeon r7 250 with 2vram, motherboard is Gygabite
but either way i don't know what to do i tried different versions of Cemu, I put in in the C drive and everything but atlast, it still doesnt work, it still crashes on startup. I am starting to get desperate

So this is my Cemu's 1.11.3 crash log.txt file :
