Final Cut Pro Export Issue (14-inch MacBook Pro M2 Max)

Hi everyone, I recently purchased a 14-inch MacBook Pro M2 Max and downloaded final cut pro on this new mac for my editing projects.

The current project I am doing includes a lot of black screens between words and images, and when I watched the exported video - it was really weird. It looks like every single word / image appeared in a very quick fade-in transition (I don't really know how to describe it).

I am 100% sure I did not add in transition between any of these images / words / clips, and there was no problem when I watched the playback in the project itself. It only became weird when I watched the exported video. BUT! When I tried to move frame-by-frame in the exported video, it had no problem either (i.e., in frame 1 there is no word, in frame 2 the word appears - which is how it should be) - but then when I played the video - the "quick fade in problem" is still there.

I am really confused. Not sure it's a compressor export setting problem, or a render problem, or the new mac's setting problem? Anyone have any ideas?
