Mac Pro keeps restarting and error pops up on screen then shuts down

Kernel Panic Reports are stored in the Folder at:

/Library/Logs/DiagnosticReports

If you copy and paste that string into:

Finder > Go menu > Go to Folder

it will take you to the Folder where those reports are stored.

Kernel panic reports are named with Date&Time and start or end in ‘panic’

If you find one, please post the entire report here, by using the “additional text” Icon in the reply footer (looks like a paper with writing).

Please don’t post more about 20 lines of any other types of reports — they are interminable, and any information useful for this purpose is on the first screenful.

The panic-reason is not on screen for that screenshot, but its occurence in mediaanalysisd suggest you have added third-party virus scanner that is crashing your Mac "to protect you".

fresh install after ERASE? what did you bring back from your backups?

fresh install over pre-existing? that does not remove items you added.
