UE5 P2 - Cannot render sequence. Crash and MOV bug

I’m trying to render a sequence that previously rendered fine in UE5 EA2.

I have tried on multiple PC’s all have mid to high specs (RTX 2080/3060ti/3090). None render.
I set the output to mov and instead of a video file I get one mov file for each frame in the sequence.

The scene is in DX 11 because DX 12 isn’t working on this particular scene in P2.

I have no ideia how to troubleshoot this or fix it. Please help
