Kernel panic information is saved in non-volatile RAM and at next startup, is formatted into a human readable report and stored at:

/Library/Logs/DiagnosticReports

Copy the above string and paste it into:

Finder> Go menu > Go to folder ...

to get there.

Look at the files there. Panic reports named with Date&Time and end in .panic

Post the most recent one, or the one you noted above, in its entirety.

Please do not post more than about 20 lines of other types of reports -- they are interminable, and the important information (if any) appears in the first screen.

You need to post the whole Kernel Panic report here using the "Additional Text" icon which looks like a piece of paper. Launch the Console app located in the Utilities folder. Within the Console app, look inside the following folders on the left pane of the Console app which will open up another pane to the right. macOS keeps moving the location of these Kernel Panic files so look in folders with names similar to "Diagnostic Reports", "System Reports", "/var/log", and "/private/var/log". The Kernel Panic file names will begin with "kernel" and end in ".panic". Post several Kernel Panic reports if you have them.

Also run EtreCheck and post the report here using the "Additional Text" icon which looks like a piece of paper.
