MuseScore 4.0.2 crashes when the last bar is removed

Hey there!
I'm having a bit of trouble with my version 4.0.2 of MuseScore, running on Windows 10 x64.

In the following situation(s), MuseScore crashes to desktop:
[Having opened the attached file; the last bar being assigned a change of beat count or however you call it in English...]

• if I remove the last bar via CTRL+DEL >>> then trying to select the bar = crash
• if I remove the change of beat count via select and DEL, then remove the last bar via CTRL+DEL >>> then trying to select the bar = crash

Note: Selecting other bars in-between the removal of the last bar and the selection of it works fine, so it really seems not being able to handle the actual reselection of the last bar, which by that time is the second to last bar.

In case it would matter in any way:
- I'm using the German version, i.e. localization
- I'm using the new MuseSounds libraries as standard loaded in the project

I hope this report is detailed enough and not too confusing.
If any further information is required, I'll be happy to provide it!
Thanks in advance for looking into it!

EDIT:
I just tried pasting a multiple bar melody in a way that it reaches into the corrupted bar and it works fine, also plays. Still, when trying to select that bar, it crashes...
