Anyone knows why the sequencer jumps to zero?

Hi,
I’ve had a problem on several different machines, and on both PC and mac, that the animation of the camera in the sequencer mysteriously jumps to some kind of “zero point” when exporting the sequencer. I’ve tried adding a new camera, make a new sequencer nothing helps. All looks good when playing the sequencer, but when I try to capture it makes this weird jump. It seems to sometimes be when I use some water materials.
Does anyone have any clue of how this could be solved? Would be very helpful.

I’m currently in UE 5.0 on a PC with AMD Ryzen™ 9 6900HX, NVIDIA GeForce RTX 3080 - 8 GB, 32 GB DDR5 RAM.
I’m exporting with the Legacy Capture in AppleProRes 4444.
