The same happened to me. After using CCleaner's Driver Updater, many programs became disfunctional, all 4 USP ports stopped working, a sheer nightmare. It seems I have spend hundreds of pounds to buy a replacement laptop. I employ a real expert for help in this matter - and all he could finally recommend is to re-install Windows 10 from scratch. The latest version is to come out 0n November 10, 2021.
This disastrous problem turned me from CCleaner aficionado to CCleaner foe.
It seems to me adding the Driver Updater created so many problems for CCleaner users that these problems now outweigh the benefits of this software.
Adding Driver Updater ruined CCleaner's reputation for a long time.
If they knew that RealTek drivers create unsurmountable problems - all I can say is why ?
