Final Cut Pro 10.8.1 Can't Even Playback a standalone 4K60 Video

Folks, I'm not sure what's going on, but FCP 10.8.1 can't play a simple 4K60 video. I'm not pushing it anyhow. No Multicam being displayed, no vector scopes, no 3D artifacts, no color adjustments, nothing. Only 4K60 footage from a Canon R7, and 4K24 footage, with the Machine Learning Video Quality applied - so we can get good slow motion - from the old and trusted Sony A7 III. I can't play the timeline, it stutters, breaks the audio, a mess. Yes, I set the Quality to "Better Performance". Even so, it still can't play the video fluid. I'm using a SSD drive, on a MacBook Pro 14-Inch, 2021 with the M1 Pro chip, 16 gb of ram and 512 gb hard drive, and macOS Sonoma 14.6.1.

Any help, anything, any assistance will be greatly appreciated. Thank you.

Is the slowmo processing complete? We're not running 10.8.1 yet, but I've heard the processing can take quite a while and the analysis files can be quite large. How much free space on your drive?
