Mac OS Ventura 13.2.1

There is no reason to ever install or run any 3rd party "cleaning", "optimizing", "speed-up", anti-virus, VPN or security apps on your Mac.  This documents describe what you need to know and do in order to protect your Mac: Effective defenses against malware and other threats - Apple Community and Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support.  

There are no known viruses, i.e. self propagating, for Macs.  There are, however, adware and malware which require the user to install although unwittingly most of the time thru sneaky links, etc.   

Anti Virus developers try to group all types as viruses into their ad campaigns of fear.  They do a poor job of the detecting and isolating the adware and malware.  Since there are no viruses these apps use up a lot of system resources searching for what is non-existent and adversely affect system and app performance.

There is one app, , which was developed by a long time contributor to these forums and a highly respected member of the computer security community, that is designed solely to seek out adware and known malware and remove it.  The free version is more than adequate for most users.  

Uninstall Avira according to the developer's instructions.

What you are showing is a kernel panic report.

These may make sense for engineers, but we need more information. Does this happen repeatedly? What circumstances seem to trigger it?

A kernel panic may be due to hardware failure or a software conflict. In order to have a chance at diagnosing this, Please run Etrecheck and post its full report here.

Use the “additional text” button and paste the report into the text box.

I am getting this error as well when powering on my Mac mini. I ran Etrecheck as you requested.

Which information from the report are you looking to see, there's lots of stuff in the report.

Thanks for the reply, but you didn't name the app you mentioned here:

Uninstalled Avira and still the same exact issue, upon power up, a crash with no successful checkins from WindowServer in 120 seconds.

I have 5 external disks attached to this mini, two directly into the USB ports on the mini, and three via an external dock. The dock is attached to the mini via the USB-C port, and inside the dock is an SSD, the other two disks are attached to the dock.

When I power up the mini without the two disks attached to the dock, the mini does not crash. Only when I try to power up with all 5 disks at the same time does it crash.

No, the dock gets its power via a USB-C port that is connected to the mini's USB-C port. The dock is an AGPTEK USB-C Docking Station & Stand for Mac Mini with SATA SSD/HDD Slot, TF/SD Card Readers USB 3.0/2.0 for Mac Mini 2018 or above.

I unplugged the two external drives from the dock, and everything powered up fine, the mini with two external drives, the dock, with its internal SSD.

It's just when I have the other two external drives attached to the dock does powering everything up at once causes the issue. I'll have to do some more testing to see if I can isolate it to one of the two drives. I have my doubts that it is a drive problem.

The weird thing is, when the crash happens, it automatically restarts, and everything works fine after that. I would have thought if it were a drive problem, then restarting would give the same issue.

Please post the full Etrecheck report, using the "additional text" button below your message:

Completed as requested.

Must be the free version of Malwarebytes. It was developed by a long time contributor to these forums and a highly respected member of the computer security community. 

Good, now you know that these drives are somehow involved. You should divide and conquer: try with drives separately. It’s possible that the problem lies with one drive specifically.

Is the dock self powered? If not that may be part of the problem.

I recommend you contact Customer Support at OWC (MacSales.com) and see what they recommend for self powered docks. OWC is considered the premier 3rd party hardware provider for Macs.
