Musescore 4.2.1 appimage(and olders v4) on linux can't be launched
I try to install and use Musescore 4 on several old pcs under Debian Bullseye in a music school
where i use it with students.
On one of them, Musescore 4 is working. But on others, I can't launch it.
I can't find what dependecy or lib is missing.
Launching it with command line gives :
