10.15.6 - Crash loop with iCloud+Google disconnects

[hiyadagon]

Yet another Catalina crash thread, but I haven't found anything mentioning this particular case.

Over the past couple of weeks, my 2020 i7 Mac Mini has been going into crash loops seemingly at random: Bluetooth mouse and keyboard will freeze, followed by a notification that I need to sign back into iCloud and Google. Then the dock and menu will crash and relaunch, with a second set of running app icons. The crashing and relaunching of the same apps will continue until I'm either able to get to the shutdown menu or hard reset the Mac.

The fact that I get logged out of iCloud and Google and need to reauthenticate after restarting is really what's throwing me off. I've already reset the PRAM, NVRAM and SMC, reinstalled Catalina from scratch, and run the Apple hardware test. No problems detected so far.

I've seen mentions of file activity being janky under Catalina and I have 4 external drives plugged in, run Plex and VMware Fusion in bridged mode. Leaning towards VMware being the problem here and overloading the network interface somehow, but at this point I'd just like to know if anyone else has had similar crashes that wound up also logging them out of cloud services.

I've had a similar problem about my mouse freezing up, having to re-sign into iCloud with icons disappearing from the menu bar and my iMac freezing up completelyforcing a hard shut down. This happened only a few days ago and beforehand I got several small windows popping up about; " .... security agent ...", " re-entering my Apple ID", "unrecoverable error...", " iCloud Drive may not work properly...",


I do not have Plex, VMware or any other devices running at the same time but did haveTime Machine plugged in.

My imac is a late 2015 27" with 24GB ram and about 1.23GB of H/d space left out of 2TB.

Are you on 10.15.6 as well? I feel like that's the only significant change to my system before this all started.
