I'm a vega11 gpu user and I've had such driver errors before and I don't want to live anymore.But when the transition from 19.5.2 to 19.6.2 system crashes occurred.I format it but it crashed again when I installed 19.6.2.EMERGENCY NEW DRIVER !!!
Welcome to my world. I have been saying this since patch 17.11. Try something for me. Try opening Media player in full screen an see if your system doesn't crash.
