someone can close this topic, thank god I found another solution to fix this from other person.
I will copy-paste how to fix this here so maybe less people would have to struggle for 2 or more days trying to fix this annoying thing
Confirmed working 100%.
Ridiculous.
Such a simple thing that could've been debugged months ago now when first reported.
Solution (for those who have never used regedit before):
First, If you have "RadeonSettings.exe" process in Task Manager, kill it ("end task"). I had to do that because once it displays the message, it silently stays running in the background. To launch task manager, right click on the task bar and "start task manager." Scroll to see if you can find radeonsettings.exe If you can, highlight it and "end process."
Go to start\run (or start\"search" if you don't have run showing)
type "regedit" without the quotes
If you've never used regedit before, you'll probably see "Computer" and then a tree of stuff underneath.
Navitage the tree to HKEY_LOCAL_MACHINE\SOFTWARE\AMD\CN
Once there, on the right side, find the string which says "DriverVersion"
Double-click on the name. A window to edit the value should pop up.
Erase the value (should be 26.some numbers I don't remember). Click "OK."
There's no need to "Save" - changes in regedit are instant. Just quit the program.
Try launching settings again - should work perfectly now.
Laugh at AMD engineers and lack of expertise for such a simple issue.
As I suspected, it turns out you don't need to use driver cleaner, you don't even need to install drivers using the "clean" option, and most certainly you do NOT need to "format your system" or "upgrade to Windows 10" - absolutely ridiculous and mostly worthless advice for advanced users.
Thanks. I'll repost in this thread if this resurfaces in the future.
P.S. To do this, I'm pretty sure you need an admin account, elevated permissions for regedit, etc. If you don't, ask the person who does to fix this :-) .
