Hey @enderarrow42! Welcome to the Forums!

Check out this solved thread that had the same issue as you are having right now:

Bug menu tabs - black screen [UE5]

For the totally black screen In the main editor window: Window → Load layout → Default editor layout For the other, reset all the tweaks you made in the Nvidia control panel ( there’s a reset button ).

I hope the above contains the solution you need!
