Is it restarting out of the blue or are you getting a kernel panic screen?
Hi, thanks for the reply. It's appreciated.

When this happened yesterday, my screen just went off. My mac was still "working" as I was on a webex call and could continue to hear and speak for about a minute. Then it shut down.

When I restarted I got the above error report.. Not sure if that helps as not aware what a kernel panic screen is?

What external devices do you have, if anything, connected to the iMac?

BTW a kernel panic screen looks something like this, although not seeing it doesn't mean a user isn't getting one:
