Crashes on version 13.0 and later (Mac)

I'm at my wits ends here. The problem started this January, when I upgrades to Sonoma, I believe. Upon upgrading to LR13, my main catalog became corrupted and no attempts to repair it have been successful.

So for the last 7 months, I reverted back to LR12, and worked off a backup.

However, I recently got a new laptop (M2 chip MacBook Pro), and decided to try LR13 on there. Lo and behold, it converted my LR12 catalog to version 13 without a hitch.

When I tried this same catalog on my desktop, however, it became corrupted again, and now even my laptop won't open it.

I've talked with at least four agents, two of whom have remotely controlled my computer, and they've tried repairing it and sent it back, for it only to become corrupted again within about 30 minutes of use (importing new photos).

Please help!
