MuseScore 4 crashes after putting a tempo marking and notating sth.

Things I do:

1.) notate a few notes

2.) pick the tempo marking 'quarter note = 80' of the text pallet and use it for the phrase

3.) Now the issue will come immediately or after you put a few more notes

The scenario:
MuseScore 4 waits for a few seconds. Then, the bluetooth sign appears on the bottom-right corner of the task bar and a little sound appears that my logitech mouse is reconnected. Afterwards, the programm closes and my headset (also bluetooth) reconnects.

The issue happens since yesterday evening. And happened 6-7 times.

I use a windows 11 laptop with 16 GB RAM and the CPU gets only beetween 20-40 % while using the programm. However the programm is sometimes a bit slow while using it and the playback is not always working when using the play button.
I am using the latest released MuseSounds libraries: Strings, woodwinds, brass and percussion.
I did not install the other libraries or some of the extensions.
