CCleaner Pro Plus stop working last week

I have had CCleaner working/running on my 64BIT Windows (c) 10 Pro XPS Dell computer since 09/11/2019 and all of a sudden it will not open. I have uninstalled it, and re-installed it several time and it will install, but won't open? HELP.

What antivirus do you use?

Trend Micro - Maxium Security Plus 2019

There's a current bug in trend micro, they are working on a fix. A work around is to Whitelist ccleaner in trend micro following the directions in this post
