MS4 Not opening.

• Mar 9, 2023 - 00:29

Hey guys, I'm working on MusesScore from my School laptop and need to write a 15-minute arrangement for our schools Second and First Stage Bands. It's not necessarily a time-sensitive project because i have until the third quarter to finish it but just as I've started it MS4 has stopped working altogether. I've tried reinstalling MS4 alone, reinstalling it with MShub and tried going back to MuseScore3 which is painful.

When I open MS4 The booting screen will open and MS4 appears in the Task Manager but after ~1 min the booter closes without a crash report. Computer Specs aren't an issue. I don't quite know what to do. Help is appreciated.

I've added a sc of what the booter looks like.

Had this issue a while ago and deleting lingering MuseScore 4 projects and audio files fixed it.

In a file explorer window, click to "View" and check "Hidden Items".
Go to This PC: C:\Users\YourComputerUserName\AppData\Local\MuseScore\ and deleted any lingering MuseScore 4 projects and audio files.


Hope this helps.
