I've now faced this issue on two of the 6 total Macs on my household. Neither with any recognizable patterns I could depict to properly find a reason as to why it happens. On my MBP11,5 it crashes the whole UI, and is unable to start again On my iMac14,1 it just shows the notification, however, the OS randomly starts to increasingly become unstable, like Safari being unusable until a restart. The best conclusion thus far has been to perform an SMC/PRAM reset on my Macbook (where it'd frequent itself like 6 or 9 times a day sometimes, all requiring a reboot), and on my iMac it happened a few minutes as I write this, so no conclusive workaround or solution has been necessary for now. My MacBook has FV2 enabled, but my iMac does not. Both are running 12.3.1, both are running on an SSD (Apple SSD on the iMac, Crucial P2 on my Macbook, which has otherwise worked flawlessly for a while). On my MacBook It has shown itself since I first installed Monterey, on 12.2 IIRC, and on my iMac it has just appeared now on 12.3.1. I'm sure It's not related (in both of my cases) to RAM, as both have healthy/working RAM, and all temps and usage are low at some points where I have observed the issue. Re-installs do not help, as I have unfortunately discovered on my MacBook (With a Time Machine backup), nor a full disk-wide wipe of the SSD (Apple SSD on the iMac was previously completely erased off all of its contents). I look forward on seeing if Apple is able to resolve this frustrating issue, as downgrading is not really an option for me, and the time loss inflicted by having to save projects and restart because I have my UI crash on me or the OS fall apart ain't fun.
