Alembic Stream Player crashes my game on a tester's computer

So, I’ve been testing my game (releasing next week), on about 40-50 machines, all without issues.
But one of my testers, crashes when loading a scene which relies on an “Alembic Stream Player” animation.
It was very weird because the game works perfectly in every other scene (my game has 100+ scenes), except that one (which is towards the end). Which is the only one that relies on Alembic Stream Player. So I made a test removing it and sending him a beta build, and, in fact, without it, my tester was able to load the scene…
Therefore, for some reasons, on his machine, Alembic Stream Player is causing a crash.
This is his crash-log screenshot (sorry for the bad quality, he sent it to me that way):

Player.log reported no bugs (nothing missing from the console, etc.).

So my questions are:

  • Why is this happening on his end? (p.s. he has the latest GPU drivers, updated DirectX and updated Visual C++)
  • How can he solve it on his end?
  • How can I solve it on my end? (without giving up Alembic Stream Player)

NOTE:
I’m building with Unity 2020.1.15f1
This is the inspector of the Alembic Stream Player:


Thank you very much for your help.

Thanks Kurt… how can I move the thread? Only a mod can do that?

I believe so. You could try reporting your own thread and asking for it to be moved.
