First I would use a Group Policy Editor (Windows Pro) or a Registry Editor (Windows Home) to block Microsoft from downloading AMD drivers.
Second I would Command Prompt as administrator sfc /scannow to check your OS file integrity. This will also repair missing or corrupted OS files and if you have malware or a rootkit this will sometimes detect those.
If your running a prebuilt or off the shelf PC you need to contact the manufacturer and create a support ticket.
You may want to create a support ticket with Microsoft as well just to check if this is a Windows 11 issue.
What brand motherboard are you running?
How long has this been happening?
Having detail hardware and OS information will help to narrow down this issue more quickly.
