i used the camera editor and was working on a manual camera fixture, and all the sudden the game crashed after the time limit ended, tried to rejoin and play the scene multiple times but it keeps crashing

Go to another world, and do like shown in this video. https://youtu.be/96_VnqywyRY?si=7UiVWp2RpikjRDHQ?t=240

That should fix the problem.

so do i just copy the recording files from the previous world and paste it into the new world? or will it bug out?

No, enter into another world, do what shown in the video, and then come back to your original mod that kicks you out/crashes you.
