If it happens on ampere then I should be able to replicate, but a reliable method of triggering the crash needs to be found. It needs to be repeatable quickly (ideally less than 1 minute) as I'd need to intentionally crash it many times in succession. Nvidia doesn't support device faul...
Unfortunately I won't have time right now to debug why the AppImage is trying to use system Qt libs, it should only be using the bundled libs. Is this error reproducible on more common distros like Ubuntu, or does it only occur on Mageia?
