Fusion page bugged

Hello!
I have a Problem with the Fusion Page since yesterday. Always when I open the Fusion Tab, the space where the Nodes would be placed is completely black if i was on the Edit Tab before and has some Color coreecting Tools on it if I was on the Color Page before. All Buttons are also those of the tab I was in before and I cant click anything besides the Tabs (Fusion, Edit, Color,...). This Problem occured only today and I reinstalled the program twice and restarted my Computer several times, but it didnt help.
I would very much appreciate it if you could help, because I am a fairly new user and have no idea what to do besides what I already did before.

If you're on Windows, are your graphics drivers up to date?

Yes my AMD Software says they are up to date. But could you tell me how to check this just in case? Because I am new to PC and I am not too familiar with everything.
But thanks for helping!
