CCleaner stops working

I run CCleaner and it freezes on 17%. I'm not sure how to fix this as I've uninstalled and reinstalled it. Any help would be amazing

What cleaning process does it freeze on? It should be displayed in the main program space while the program runs

This is all I see and it stays here

Akidna try unchecking thumbnail cache (just temporarily) and see in it still freezes. Also kudos for the tardis

I would say for now, untick the Thumbnail Cache entry in the cleaner and run it again, looks like a jammed chameleon circuit to me
