Finder is broken
The finder on my iMac is not responding. What is happening? I don't understand this and a "good old college try" at restarting this is pointless......
iMac 27″, macOS 10.13

If WheelieNick's guidance doesn't work, force a restart by pressing and holding the power button until the computer shuts down.
If it happens again, shut down and restart in Safe mode (press and hold the shift key down at startup). It can take much longer to safe boot (5 min) so be patient.
How to use safe mode on your Mac - Apple Support
Safe mode is non-destructive to user data. It’s not a cure-all, but very often corrects weird software behavior by forcing the OS to do cache clearing and other housekeeping. When you're in safe boot, the machine will not be at its best performance, especially with graphics, but that's expected.
Does the problem persist while in Safe mode?
Allow the computer to "soak" in Safe mode for a couple hours, then exit safe mode by restarting your Mac normally and re-evaluate the issue again.
