Frequent kernel panics on Mac Pro running 12.3.1 – help deciphering panic report?

[probedaddy]

My Mac Pro (late 2013) has had occasional kernel panics for a while, which have become much more frequent lately.

Often these will occur when I am not actually at the computer – sometimes when I'm leaving it to export videos (Adobe Media Encoder) or other times when it's doing nothing at all in the foreground. Both when sleeping and when awake.

The other day it started panicking about every 10 minutes, so I wiped it, did a clean reinstall/upgrade (from Big Sur to Monterey 12.3.1) and restored my data using Migration Assistant from a Time Machine backup. This considerably reduced the frequency of the panics and I was able to do intensive tasks like video exports for longer periods, but it is still reliably panicking at least once a day.

The most recent panic report is below. I struggle with deciphering these and would greatly appreciate any help anyone can offer.

In terms of hardware, I'm using a Magic Keyboard A1644, Logitech M337 Bluetooth Mouse, and Samsung C27F398FWU HDMI Monitor, and my hardware overview is as follows:

This is the most immediately useful part:

Process name corresponding to current thread (0xffffff8b978e8000): crashpad_handler

In this panic, at least, it was the process called "crashpad_handler" that caused the panic. Do all or many of your panic reports specify "crashpad_handler"?

I did a very quick search and it appears that a process by that name is related to Google Chrome, or maybe chromium-based browsers (there are several). One posting suggested other third-party applications like Skype and Zoom might also use it, but gave no details (https://discussions.apple.com/thread/252521883).

That might be another clue, something wrong related to Thunderbolt.

Thanks for your help Brian.

I have Chrome and Zoom installed but rarely use either, so I uninstalled both yesterday. No crashes until just now, the computer has been sleeping all day as I haven't used it in about 8 hours, and I just heard the startup chime from the other room.

This time I got the following error report:

That might be another clue, something wrong related to Thunderbolt.

Interesting. I've never used any Thunderbolt devices on this computer. All it typically has plugged into it is 2 external SSDs via USB-A and a HDMI monitor (and sometimes aux headphones)

I think Thunderbolt and USB have the same controller and the external SSDs might cause the problem.

This time I got the following error report:

That one looks different; I've never seen one that looked like that! It looks more "hardware-ish" to me. But I'm not expert. And unfortunately...

Process name corresponding to current thread (0xffffff953dc8e550): kernel_task

...doesn't help us much, as that task is a normal integral part of macOS. : ( I'm out of ideas, at the moment.

I am having a similar problem. Can someone help point me in the right direction as well?
