    Description

      I see such crashes among our users crash reports. It's never reproduced for me locally and I have no idea why this may happen for end users.

      Unhandled exception at 0x0000000000000000 in minidump (12).dmp: 0xC0000005: Access violation executing location 0x0000000000000000.
