Hello,
Sorry to read this.
- Can you share the scan logfile?
Then, can you relaunch AdwCleaner, click on Tools -> Options and tick "Debug" in "Mode" section.
Do a scan and a clean, the crash should still occur. Simply exit the freezed window. Then, host the file "C:\AdwCleaner\AdwCleaner_Debug.log" on https://up2sha.re/ and copy/paste here the generated link.
Best regards,
