The AMDRyzenMasterDriverV19 service failed to start due to the following error:
Cannot create a file when that file already exists.
This is the only error in the Event Viewer when this problem occurs.
This was happening yesterday during Forza Horizon 5. I can't make it beyond the intro sequence because my PC hard shuts down.
Spent several hours troubleshooting. RAM tests, power supply swapping, all temperatures are great. Literally all other games are playable without issue.
So this morning I reinstalled windows with the latest AMD drivers and it's still happening. I never even had Ryzen Master installed pre reinstall, and definitely not post reinstall.
I could never play Forza Horizon 4 either because it also shut down my PC in a similar hard shutdown fashion, but I don't remember the errors from that time.
