MuseScore4.2.1 crashes

• maalis 22, 2024 - 13:35

MuseScore 4 suddenly crashed and restarting just shows the initial empty canvas and crashes again. It won't start.
I'm using a 7 yeadr old HP ENVY Win 10 with plenty of RAM and Disc available.
Rebooting, reinstalling, repairing, removing and reinstalling won't help.
I even deleted MuseScore4 related entries from registry before reinstalling. No help.
Does anybody have any idea how to get my MuseScore4 runnung again,
MuseScore3 works fine.


Does this happen only when you try to open specific files, or does it always happen?

Have you recently made any notable changes to your computer, such as changes to the audio configuration? If possible, try to revert them.

If that isn't the case, you could try factory resetting Musescore from the command line. Open a command prompt and enter or paste the following command:
"%ProgramFiles%\MuseScore 4\bin\MuseScore4.exe" -F

Edit the file path in the command if you have installed MS in another location than the usual one. Now, restart your computer and try to open MS. If it still doesn't work, please do the following:

  1. Open File Explorer.
  2. Navigate to C:\Users\%USERNAME%\AppData\Local\MuseScore\MuseScore4\logs (where %USERNAME% is your username).
  3. Attach the newest log file to your post here.

There seems to be something wrong with the part scores. I opened the file as a zip archive and deleted the folder "Excerpts", which contains the parts. Then the score opens perfectly. Unfortunately, any formatting changes made to the parts will be lost with this method.

Musescore should, however, never crash. If you have the time, I would recommend that you report this bug on Github and provide a link to the score in this topic.
