My new iMac with Catalina os fails to restart often when "restart" is selected. The apps disappear and the background stays on the screen, and the only course is to turn off the iMac in the back. I remember on my old MacPro there was a key combination with the on off switch which restarted the computer. Any solutions? Is this a problem with Catalina?

If the situation is not improved after completing the Safe Mode start, and subsequent normal restarts, try downloading/installing the macOS Catalina 10.15.7 Combo Update.

You are using a lot of Extensions which might prevent your system to showdown or restart. Etrecheck report shows various driver extensions for Seagate, Western Digital, Lacie RAID and ParagonNTFS. It looks like you have migrated to Catalina without upgrading your Third-Party software. Some of your aplications seems to be outdated or incompatible with Catalina. CleanmyMac installs adware and slows down your computer. Flash Player is no longer needed. It's an insecure and dangerous piece of software. As recommended you should uninstall them. Uninstall Adobe Flash Player, Uninstall CleanmyMac

Uninstall CleanMyMac per their directions , then run etrecheck again to see what chaff it left...

This sounds like Finder hanging issue which might be caused by one of the your driver extensions.
At least, I do recommend to update your apps to the latest version. Some Extensions need to be compatible with Catalina. CleanmyMac is well known for causing various new issues. It's up to you.
Do you use any external hard drives? If so, try to eject those volumes prior restarting.

Remove CleanMyMac, and Adobe Flash Player using the developers instructions.
Could you share a etreck report? Make sure to enable full disk access.
Tom, it is sporadic. Sometimes it restarts, sometimes it just freezes and does not restart, with or without external drives mounted.

I could not open the cited page. Why do I need to delete these applications?
Thank you Tom. The extensions seem to be connected to my external drives. I will take your advice but I am a little hesitant on Clean my Mac software since I just bought it.
Catalina on Mac often does not restart
