Got a tip for us?

I did experience the issue too but i updated to OSX Big Sur 11.3 beta 8 and for me, the issue seems to have gone.
I had the message in Beta 7, installed Beta 8 and still had the message, started in "Safe Mode" and back to normal Boot with NO message. PS never had a KP before or after.

you've booted in safe mode, and/or reset nvram? haven't seen that message again in a long time now. what other 'staggering' bugs have you experienced in apple's OSes? start a thread, perhaps, see if anyone here can help.
Never had this issue until now. Only Since a clean install of Monterey. Also, with very little else installed on the computer.
Now, after every scheduled and or manual restart or shut down a dialogue pops up saying it was shut down because of a problem.
Tried resetting NVRAM with Command+Option+P+R and a safe mode reboot. While the message didn't appear in the actual safe mode reboot the subsequent regular boot it was back in all its buggy glory. Anyone ideas?

I had the same problem in Catalina, running OnyX maintenance fix it.

It's probably the cleaning of system kext caches, that can also be done from Terminal.
Titanium Software | Operating System Utilities for Mac - OnyX
OnyX is a multifunction utility that you can use to verify the startup disk and the structure of its system files; run cleaning and computer maintenance tasks; configure some hidden parameters of many Apple applications; and more.
Thanks for chiming in. So I tried cleaning Kext Cache through the terminal and had no luck. Downloaded Onyx, ran the default maitenence, and bingo! No more dialogue on restart. I Will see if it sticks. Only wish I knew what the culprit was. Thanks again!I had the same problem in Catalina, running OnyX maintenance fix it.

Just to note, I've started seeing this problem on my iMac (27" i5, 2019) running macOS Monterey (12.0.1).
The only coincidental is that I did see a kernel panic last weekend, but everything seemed fine after that restart…
The last few normal restarts have consistently shown the "You shut down your computer because of a problem" at login.
I will try the Safe Mode boot, and NVRAM reset.
EDIT: tried both Safe Mode boot (which took a few goes to actually activate, and bizarrely only worked with the right shift key) and an NVRAM reset. Neither resolved the error message.
But, as per the tip from @bogdanw , running the 'Maintenance' ▸ 'Run Tasks' feature in OnyX worked a charm; the error message is now gone when I log in to my Mac. Thank you! 🖥😃

Also worth noting that the issue hasn’t been back either.
I had this same issue in Monterey. I did the Onyx trick above and the message is gone and staying gone so far. Thank you!!

Thank you all for this thread, as I recently had this problem on my 2017 iMac with Monterey. I also did the Onyx trick, ran the default maintenance and no more dialogue at startup. Cheers everyone 
Ok, never mind, this solution worked for me!
Deleting a "Sleep Wake Failure" diag file in \Library\Logs\DiagnosticReports that was closest in time to the start of the problem.

There are many reasons that cause the Mac system randomly shut down, few of the main reasons are:
1. Shut down your mac properly
2. Run Disk Utility
3. Check the battery health
4. Check for malware
5. Update macOS
Hope it helps!
- Depleted battery
- Outdated version of macOS
- Disk and software errors
- Peripherals causing malfunction
- Kernel errors caused by third-party apps

Old thread, I know, but came here to say I just ran into this issue on my M2 MBA. Reboot, safe start, disk utility, re-install OS via recovery — all failed and the issue persisted. Ran maintenance on Onyx and it fixed the issue.

not necessarily, when it happened to me it was the macos, when i went to the next macos everything was fine.
