Getting blank custom workspace when changing form another workspace to one of my own
Whenever I switch to a custom workspace that I created from one of Adobe's or another users, I get a blank workspace with no panels at all.
It appears it's a bug that isn't saving the workspace or not allowing you to access a custom one when switching from anothers.

It sounds like you workspace might be temporarily corrupted. Did you try "Reset to Saved Layout"?
