Kernel Panics on a 2018 MacBook Pro running 13.4 Ventura!

Refer to If your Mac restarts and a message appears - Apple Support.

Diagnosing kernel panics is often an exercise in trial and error. The most likely culprit is hardware, so disconnect any external drives that might be a contributing factor. Use the Mac long enough that way to determine if the KP events persist or subside.

There is nothing amiss with the number of drives shown. Only one of them is external, so try disconnecting it first.

Post several of the Kernel Panics here using the "Additional Text" icon which looks like a piece of paper. You can find the Kernel Panic logs in "/Library/Logs/DiagnosticReports" folder. The Kernel Panic logs will have file names beginning with "kernel". If you don't see any Kernel Panic logs in that folder, then check the "Retired" subfolder.

We need to see several of them to see whether there is any pattern to them. Unfortunately the EtreCheck report did not show anything useful in the summary panic logs it included which can happen sometimes. Hopefully with several of the complete logs will have some useful information.

Agreed, definitely an issue with the GPU (panic logs indicate GPU Restart). Either it is an external Display issue (or possibly other externally connected device), or it is a GPU hardware failure with this laptop. If your display has multiple input options, then perhaps try using a input connection (or maybe try a different video cable and/or adapter).

Disconnect all external devices in case one of them is causing a problem or a compatibility issue with the display.

Also try connecting the external display to another USB-C port especially on the other side of the laptop.

No panics in Safe Mode, although everything runs a bit anaemic as expected...

Uninstall either of the two kernel extensions using the developer's uninstaller.

If the panics stop, that was the cause. If not, uninstall the other. If the panics stop, you can try reinstalling the first.

I have that connected now and it seems to be okay, went one evening without a kernel panic. I will keep testing but if I narrow it down to one port on one side, would that most likely be the port itself rather than the logic board given that the adjacent port still works.

Hard to say, but usually it will be the I/O Board that is bad (usually damaged). In my experience supporting our organization's thousands of Macs, I find that the USB-C ports tend to become damaged from liquid (sometimes from other things too)....just takes a single drop splashed on the table nearby to get inside the port to cause damage.

If it is not the I/O Board, then it would be the Logic Board. Sometimes third party connected devices can cause a failure of the USB and/or power circuitry on the Logic Board for the USB-C port (each port has its own USB/power circuitry on the Logic Board).

Start up in Safe Mode and see if it panics. If it doesn’t, the cause may be the Cisco kernel extension or the FTDIUSBSerialDriver kernel extension.

As an external device, the USB-C/VGA adapter is a possible cause. Leave it disconnected long enough to draw a conclusion.
