Mac Trash emptying slow after moving CleanMyMac folder

I'm trying to delete the following folder: /Users/myName/Library/Containers/CleanMyMac/tmp

prior to completely uninstalling CleanMyMac from my Mac mini M4.

I moved the Users/myName/Library/Containers/CleanMyMac/tmp folder to the Trash and tapped on Empty Trash. The operation has been running for hours and, so far, it's saying it has deleted over 4.5 million files and it's still going and showing no signs of stopping any time soon!!

If I stop it, will all those files lose be unmarked as deleted? If I restart emptying the Trash later, will I be starting all over from scratch?

Searching on some filenames I saw during CleanMyMac's Deep Scan for malware is how I tracked down this tmp folder.
