Adding a trombone part make Musescore 4 crash

Hello,

I have a musescore file with several parts. I want to add a trombone part. It's possible to create it but almost every time I try to add a note or simply click on the stave (the trombone one), the app crashes immediately.

I downloaded a chart i found on musescore to win some time and I'm adding horn charts on it. So, I didn't create the original file. But I had no problem with the others parts i created...

I've done other file with 0 problems and with the same config so i guess this file has a problem...

This makes me crazy, please help me to debug this :D
