[Linux] NativeApplication.nativeApplication.exit() sometimes cause crash

[itlancer]

Problem Description

NativeApplication.nativeApplication.exit() call sometimes cause crash for Linux devices.
I cannot isolate it in sample cause it happens in complex applications only in ~5% of application closes. May be it somehow relevant to audo playback (or even attempt of playback non-existing audio file via Sound class). May be it happens when application launched under sudo (even without workarounds mentioned here #3450).

Tested with multiple AIR 51 versions, even with latest AIR 51.1.3.1 with multiple different Linux x86_64 devices (physical and VM), different OS versions and different applications.
Tested with multiple Ubuntu x86_64 22.04.4 LTS and Ubuntu x86_64 24.04.1 LTS devices with different window managers.
Same issue in all cases.
There is no such issue with other platforms.
