CCleaner cannot close Google Chrome

Hello,

Just recently, when I run CCleaner, it is not able to close out Google Chrome so not all of the "Junk" is being cleaned. This just started in the last few days. I have Googled (haha) solutions, but none of them seem to work. I tried Chrome>Settings>Advanced>turn off background apps, but no change. I have uninstalled and reinstalled both Chrome and CCleaner to try to fix the issue - no help either. Any suggestions?

Thanks.

Dan
