I too have Windows 7 (Ultimate) SP1) and have just updated CCleaner to ver 6.11.10435 and the scan crashes towards the end, however, I've managed to get mine to complete the scan by unchecking TEAMVIEWER in the Ultilities section, something I noticed you have installed in your screenshots and yours is checked.
Hope this helps

the Teamviewer version is 15.37.3 , and before anyone says it should be updated, I can't!! its used with a dedicated PC in the workshop running old software which cannot be updated.
