For me it was this what worked, that I found on this page:
https://pupuweb.com/remove-amd-software-adrenalin-edition-context-menu/
Basically add the String with name {6767B3BC-8FF7-11EC-B909-0242AC120002} and value AMDSoftwareAdrenalinEdition to this key: \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked
If the key doesn't exist, create it.
