Having the same problem. It seems like my computer has been kernel panicking in its sleep.

I had the exact same problem, once my iMac booted up I done another restart myself this seems to have fixed it!

The issue resolved after last mac os update

I have the same problem after putting my Retina 5K iMac to sleep and then waking it up. Latest Mac OS update is installed yet this problem persists. It's one of a number of extremely bizarre problems I've noticed since updating. Another is that the option to unlock my iMac with my Apple Watch is not present on the Security and Privacy tab of System Preferences. To get it back, I have to reboot, sometimes more than once, and then it reappears. While it's gone, my Watch will not unlock my iMac.

I'm noticing tons of other random issues too and am becoming impatient with this year's software across the board.
