Fedora build of 4.6.3 unable to load MuseSounds

Issue type

Other type of issue

Description with steps to reproduce

Greetings. I maintain the Fedora musescore package. Fedora 43, to be released next week, will make 4.6.x versions available to our users. However, an early tester reports that MuseSounds does not work:

https://bugzilla.redhat.com/show_bug.cgi?id=2404987

I can reproduce this with a build of 4.6.3 for Fedora 42. Control reaches muse::musesampler::MuseSamplerLibHandler::init() and passes the first test (that initLib is non-NULL). Then initLib() is called and does not return ms_Result_OK, so logs the Could not init lib message and returns false. I can't debug this issue, because libMuseSamplerCoreLib.so has a missing symbol, DRM::AntiDebug::scheduleThreadTimedCrash. Since you have deliberately prevented me from debugging the issue, would you please debug it for me?

Supporting files, videos and screenshots

In which versions of MuseScore Studio is this issue present?

4.6.0 - 4.6.3

Regression

Yes, this used to work in a previous version of MuseScore 4.x

Operating system

Fedora 42, 43, and Rawhide

Additional context

Fedora 41 and 42 don't provide MuseScore versions later than 4.3.2, because Qt issues made 4.4.x and 4.5.x unusable. To reproduce, you will probably have to acquire a Fedora 43 installation, or else do you own Fedora 41 or 42 build of a source RPM like I did.
