Do a driver wipe.
Uninstall "all AMD software" using the same software you use to install the drivers.
Restart, and install 12.4.
Restart, and your good to go.
Just tried that and also tried 12.3 just in case it was a 12.4 issue. Still no luck
So you uninstalled ALL AMD SOFTWARE, and your CCC did not get removed? Or what? More details please.
