Greetings,
Can you activate the debug mode and start a cleaning process until it hangs? Then simply close AdwCleaner, launch it again and share us the debug logfile.
Here's the documentation if needed: https://toolslib.net/forum/viewthread/182-en-adwcleaner-documentation/
Do not hesitate to tell me if you don't understand something. :)
Thanks!
Regards.
