Replay Editor crashes into slow motion and prevents adding keyframes

Hi, I’m having trouble with the Replay Editor and it’s been weeks now. I’m on Xbox Series S, and at this point I can’t add keyframes at all. Every time I try, the clip goes into slow motion and I have to feather RT just to get normal speed. I mainly play to create content and make clips, but right now I’m basically stuck just claiming my ticks and doing a couple challenges, which gets boring for me. Any help would be appreciated.
