Platform information

• OS: Windows

Additional context
On one occasion I first undocked the panel on the main screen before moving it onto the second screen; this worked and did not result in a CTD (panel scaling was slightly off, though). I tried to record this behavior and now only experience a CTD:

Moving the note input toolbar does not result in a CTD, but the toolbar does not function (it was draggable post move in the recording, but this doesn't always happen) and the scaling is off (related to #9505?). When restarting Musescore, the toolbar appears on the second screen scaled correctly and fully functional.

Undocking the panel on the main screen and then moving it across did work at first, but now results in the same behavior:
