We fixed google/ExoPlayer#10838 in Media3 1.2.0, which looks very similar. So just to double-check - you are seeing this on version Media3 1.2.1?

[tonihei]

I found the likely reason for this issue that still exists even after the linked bug was fixed. The linked issue only fixed it for immediate player.prepare() calls after an exception. But if the new playback attempt happens at a later point, this problem can still happen.

Hi @tonihei , sorry for the late response but yes we are on 1.2.1.

I see you found a new possible cause, thank you for looking into this!

The commits above should this the issue I believe (will be released with 1.4.0-alpha02). If you are seeing it again after this release, please let us know.
