Premiere 2024 Constantly Crashing

Premiere keeps crashing upon opening a particular feature film project that I recently inherited. The project will remain open around 20-30 seconds and then crash, even if I don't touch anything at all and let it remain idle. There's an interesting clue here that might allow somebody more technically savvy to help me out. Here's the whole deal:

After trying the usual fixes (updating my OS, updating Premiere to the latest version, and uninstalling/reinstalling Premiere), the next thing I tried was clearing the media cache. When I opened the project back up, no crashing! Things ran a bit slower because it was doing a bunch of conforming and generating peak files in the background, but everything worked. After having a 4-hour work session, I left the project open so that it could continue to create the cache files it needed to. I came back to the project an hour later, it was all done, but the program monitor was stuck and resetting the workspace wasn't fixing it, so I closed the project. When I reopened Premiere, the project crashed again! And again, and again, and again. I had a client coming the next day, so in a panic, I tried clearing the cache again so we could at least work. Once again, clearing the cache worked and, once again, once the cache files repopulated and I reopened the project, it started crashing again.

The previous Assistant Editor had synced everything using Multi-Cam, which the previous editor said was a nightmare, so she made Merged Clips (which are also a nightmare in their own right, especially when it comes to delivery, but it's working for now). She used these Merged Clips on the main timelines, but I even tried deleting the AE's Multi-Cam folder so Premiere didn't have to create cache files for those complex sequences. Still got the crashing. I could technically finish this project by continuously emptying the media cache and having Premiere repopulate, but that is 1) a pain because it makes everything slower and 2) doesn't sound like a very safe way to conduct oneself on a feature film project.

Here are my specs:

-2023 MacBook Pro
-24 GB RAM (this has been plenty on every other project I've tried to run, even playing back native 4K)

-Apple M2 Chip (which has 10 cores, I believe)

-The footage and project are on a 12TB OWC Thunderbay 4 Mini configured to RAID5 (1.3TB remaining space, so plenty there)

-The footage is all 4K .mxf files from a Sony F55. Playback hasn't been an issue at all. I play things back in 1/4 res.

Again, things ran without any major issues while the media cache files were being created, so I don't think it's a hardware performance issue. It would seem to me the problem lies in the cache files, but that whole world alludes me. Any help would be sincerely appreciated!
