Issue: Fleet of Macs frozen after any login attempt

Hardware affected: Fleet of 50+ Intel Mac Pros [Sequoia/Tahoe], Mac Studios [Sequoia/Tahoe], and Mac Minis [Tahoe].

Okay y'all, this is my first post here and I am finally out of ideas. We've had an intermittent issue for about the last 2.5 years (from Monterey through now Tahoe) where our Macs freeze and beachball on login, with the clock also freezing. The only way to break out of it seems to be a hard-restart. I can boot into recovery, but Safe Mode exhibits the same behavior and freezes. Local admin and test recovery accounts can't seem to log in either and freeze the same way. I've also attempted clearing auth.db and other caches, even trying to trigger Apple Setup again, all to no avail. It seems that no matter what I've tried, I eventually just have to do a full wipe/rebuild and frankly, I just can't afford the time to rebuild every one of these manually each time.

Quirks/Other Info: Anecdotally, it seems to come in waves, eg 6 machines did it last week and 3 did it this week, while sometimes we'll go a weeks/months without issue. Additionally, some machines will occasionally get themselves on a reboot loop when exhibiting this behavior, but all of it seems to be cleared when I wipe/rebuild the machine.

At one point, I had just been re-imaging via Disk Utility in recovery, which seemed to work for a while then continued the same behavior down the line. Additionally, I had tested switching certain machines from AD to EntraID for authentication and it seemed to correct the issue for a while but now makes no difference. I also haven't seen any issues coming from JAMF's side either, as several other machines at the organization are totally fine. Everything seems to be fine until all of a sudden it doesn't.

Has anyone else seen or heard of any similar issues?
