Checking to see if anyone has more information on this issue or how to fix it. Issue UE-131432 first reported it.

This only started happening since we transitioned from 4.26 to 4.27. When we play the sequence, the game (both PIE and packaged) freezes for a few seconds.

When seeking through the Sequencer timeline in the editor and hitting the playback, it freezes for multiple second while trying to fetch the video samples and then hits the timeout on line 1922 of MediaPlayerFacade.cpp, printing “Blocking media playback timed out. Disabling it for this playback session.” to the logs.
