Description
I see such crashes among our users crash reports.
Unfortunately I have no minimal reproducer at the moment.
Unhandled exception at 0x00007FF8B492DB95 (Qt6Core.dll) in minidump (34).dmp: 0xC0000005: Access violation reading location 0x0000000000000030.
Stack:

This code looks weird, pay attention that mediaStatusChanged() is not a signal (why emit?), it's just a regular method of QPlatformMediaPlayer.
Note: as soon as I can see and may trust to minidump, m_session->status() is EndOfMedia at the moment.
