CCleaner stopped working

A few days ago, CCleaner stopped working. MacBook Pro running Mac OS Catalina 10.15.4. CCleaner Pro 1.17.603.

The automatic cleaner has stopped and when I open CCleaner for a manual clean (even the very simple stuff) it just hangs. Canceling doesn't work, I have to quit the application.

I have uninstalled and re-installed - nothing changes. What can be wrong??

I have the same issue.

macOS Catalina Version 10.15.5

CCleaner Pro 1.17.603
