I just found the thread after hitting the same issue. Was quite surprised, as macOS without iCloud is very limited... many reasons as given above.

I am seeing the same - at least daily if not more often.

Any tips on this? I'd really like to be able to at least get a pointer to what could be wrong. Here's an example of the begining of the file: {"timestamp":"2021-11-29 07:36:36.00 +0000","bug_type":"210","os_version":"macOS 12.1 (21C5039b)","incident_id":"3E1E5703-01AC-4D50-86C8-8B1C811874B0"} {"macOSProcessedStackshotData":"RGF0ZS9UaW1lOiAgICAgICAgMjAyMS0xMS0yOSAwNzozNDo1NC42ODcgKzAwMDAKT1MgVmVyc2lvbjogICAgICAgTWFjIE9TIFggMTIuMSAoQnVpbGQgMjFDNTAzOWIpCkFyY2hpdGVjdHVyZTogICAgIHg4Nl82NApSZXBvcnQgVm

I've just tried STP 127 hoping this might be fixed - but now I can't see tab groups at all - indeed other design changes found in 126 appear to have gone

Unfortunately this makes them rather useless for me for now as my lovely curated groups all disappear on exit :-( I get it's good to get the idea out there for devs to test, so maybe the rest isn't ready yet, but a release note reference would have helped if so.

I've had the same here on a 2016 MBP. I mostly use an external screen. It's occasionally come back (once without rebooting), but mostly is missing. The settings look correct. Not a massive issue, but annoying

Thanks for posting -- will try that I too saw it with iTerm2. I was using zsh (from homebrew). Switched to zsh (macOS) and same issue. Was about to switch back to bash to see if it occurs there, but will try this fix first. When it occurs there's no way out except a reboot . A 'ps' never completes, sudo etc fails - it's pretty fatal. Presumably some kind of resource or ipc issue?

It appears the public beta is available from searching for other posts via google.I do have time machine, so I could back off - but my preferred approach would be to reinstall 10.5.5 -- but I note the app store catalina installer is now updated to the supplemental version. As a public beta user (free dev account) I don't think I can download prior versions, and I would also assume that if I do a system restore, the supplemental update version will be installed. The old version provided by my mac is likely too old, and I'd be worried it could mess things up too bad.So it's probably a case of waiting until apple either re-release this update, or do something in the metadata that means it is seen by supplemental users, or the next update :-( I would assume one of the first two as this must be affecting many potential upgraders to the beta? Since most WOULD have installed the supplemental update?

Does anyone know if the public beta is available yet? I too applied supplemental so figuring out if it’s worth backing off to try update I only have a free profile and public beta profile so no point if it isn’t released on that channel yet
