Neither @zacjansheski nor I can reproduce on macOS.
Will check on Windows, but I suspect this might be specific to your environment (or a Linux-specific issue).

[MarcSabatella]

I can’t reproduce on Debian with the 4.3.2 AppImage or with the latest nightly build (using “xcb” mode; I can’t run using Wayland). But based on the pathname shown in the log, this appears to be a self-built installation, and maybe it’s really a build issue?

[zacjansheski]

No issue on Windows or Ubuntu.

Please confirm if it is a build issue

Might also help to know what plugins are enabled

Maybe you can debug and get a stack trace?

hi, sorry for not replying. I just had my examination session last week.
I have no idea why this could be a build issue, but I'll give it a try in a moment

well... to be honest... I didn't expect this issue may point to nvidia driver... why would it?

Let me check an official appimage to check if it is a problem with my build...

[gucio321]

confirme, same issue on latest .appimage

[cbjeukendrup]

Just realised that there might be a connection to #23399, which in turn might be connected to #22369

[gucio321]

well I'm using neither fullscreen nor windows but.. maybe...

[cbjeukendrup]

@gucio321 You could try if #23438 fixes it (see https://github.com/musescore/MuseScore/wiki/Downloading-and-running-test-builds#downloading-builds-from-pull-requests for how to download the PR artifacts). Slim chance indeed, but we can try at least :)

I also ran into this problem on flatpak and then while troubleshooting latest AppImage (MuseScore-Studio-4.3.2.241630832-x86_64.AppImage) , and consequently found this issue. I tried the build artifact from #23438, but the same issue occurs. I am also running Nvidia graphics on a Wayland desktop environment.

For the sake of troubleshooting, I loaded up a secondary device using the same distro with essentially all the same settings but relying on Intel graphics instead, and I am unable to reproduce the same crash on the same latest AppImage. I think it's safe to say the issue is somehow Nvidia-connected.

[cbjeukendrup]

It would be worth checking if this is any better in the master nightly builds: https://musescore.org/en/nightly-builds
These are namely using Qt 6 instead of Qt 5, and Qt 6 has allegedly some big changes w.r.t. graphics. So perhaps that changes something.

Still reproduces (8e3b4f2), so no luck with the easy fix. This is the terminal output at the point of the crash, which is consistent with earlier tested versions, and which inspires fear in the tester brain:

edit: this doesn't seem to be confined to the Plugins menu, something about the Diagnostics menu also triggers the same crash.

double edit: None of the CI/nightly artifact AppImages run without sudo, only the release version, but I'm assuming this is due to some sort of debug tooling and not relevant to this issue.
