Repro:
- Open an empty baseplate. Make sure that F5 is bound to Play Solo and Pause Scripts (these are studio defaults).
- Press F5 in quick succession.
The result is that you will be stuck in play solo. This forces you to restart studio.
Notice that, in the following screenshot, both Play and Stop buttons in the ribbon bar are disabled. Pressing Shift+F5 (default hotkey for Stop) does not work.
I am using Windows 11.
