I have an issue where the entire editing workspace just disappears. See screenshot:
The only thing I can do is go to Workspaces and choose a different one. It seems to be related to specific projects. So far I've run into it with three different projects. I can open other projects and use the Editing workspace just fine but once a project starts having this problem it always has it. Neither restarting the program nor the whole computer fixes the issue. I haven't been able to determine what it is that causes it to happen or why other workspaces continue to function normally.
Go to workspaces/reset to saved layout. May take doing a couple times.
