    Resetting the Layout to Default has also worked for me. Here's a small Hint though:
    If you don't want to lose your custom Layout, save it using "Window => Layouts => Save Layout to File" before you do the Layout Reset. At least in my Case I could re-import the saved Layout afterwards and the annoying Exception Error was gone. Good Luck! :-)

    It was present in 2020.3.2f1 - Resting the layout solved it

    Was also seeing this in 2020.3.2.

    Reset my editor layout to Default and it seems to have resolved it

    I have Unity version 2020.3.2f1 Personal, I think this bug could be back.
