    Description

      I just see such crashes from users in our reporting system.
      Most probably depends on hardware/driver, so it's not reproduced for me locally.

      Unhandled exception at 0x00007FFAF7776C99 (Qt6MultimediaQuick.dll) in minidump (33).dmp: 0xC0000005: Access violation reading location 0x0000000000000000.
