Unable to draw in Harmony 12

I have no clue why, but when I try to draw or use any tool in either the Drawing or Camera view my cursor simply turns into a prohibition symbol.
Nothing that’s been suggested so far has helped: I’ve tried selecting the keyframe both in the Timeline and in the XSheet, I’ve tried adding a Color Card, I’ve created an Empty Drawing and tried drawing on that, and several other things as well.
Does anyone have an idea as to why this is happening and how to fix it? I’m starting to notice that I am not the only one that is having this issue.

++++++++++++ same problem help please
