Kinda understand your problem with your GPU drivers but first can you please post your computer information like Make & Model of your Motherboard, GPU, CPU, Type of monitor you are using and how it is connected to your PC (DP or HDMI etc), plus Windows version (Home or Pro), and AMD Driver version installed.
Second can you post the exact AMD Driver errors you are getting when you are having problems?
Third it was a good step in disabling Windows 11 Driver update from installing drivers on your PC. Many times Windows driver update will install a different driver than the one you current are using causing conflicts and problems with your GPU card.
What exactly happens or what were you doing at the time , when you start losing video output from your GPU card (Black screen)?
NOTE: you English translation is good enough to understand.
EDIT: Why are you not allowed to go to any other Forums for help?
