Unity 2021.3.18f1 Android build crash at runtime

Unity Engine

Hi all,
can anyone help with this Unity crash backtrace stack?
I think it’s something related to the media player, but I cannot figure out more.
Thanks in advance.

Looks like it’s just a nullref. Go fix it! Here’s how:

How to fix a NullReferenceException error

https://forum.unity.com/threads/how-to-fix-a-nullreferenceexception-error.1230297/

Three steps to success:

  • Identify what is null ← any other action taken before this step is WASTED TIME
  • Identify why it is null
  • Fix that

Yeah, I saw that but with Unity 2020.x this did not happen, neither on editor I got any error.
I’ll check better, maybe something got wrong on editor upgrade.

Using the stacktrace utility seems to be something related to the video player: in fact the crash happens after a while a video starts playing.
