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.
Something very wrong is up with 16.6.2
