Bug PP v 14.5.0 (build 51)
I use double monitors, on the second one I have Project, effects and Effects Control panels set as a custom workspace.
After the last update, October 2020, I can't move elements from folder to folder in the Project panel nor drag and drop from File Explorer in to project panel.
If I switch to default workspace and then switch back to my custom workspace (which I use for years) all is working: I can move files around and drag and drop files from the OS.

I am experiencing the identical issue. Thanks for the workaround! Very helpful.
