The attached 105 frame PNG image sequence ( 1920x1080 w/alpha ) crashes the editor in UE 5.3 and 5.4 when played in the media player or in a MediaPlate. The same image sequence does not crash the editor in UE 5.1 so it is regressive.
I have attached the error logs.
Below is the segfault:
Playing the provided image sequence crashes the engine.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-195499 in the post.
