Unable to Clean error

[Scifix]

Cleaner 7
I get the following error “Unable to Clean” Some items couldn’t be cleaned. Try again or see our support article.

So I go to help and there are no entries for the wording displayed in CCleaner’s own error message, which is dissapointing, or any indication which support article it refers to unlike Microsoft that usually generates an error code to search on.
Rebooted my Windows 11 laptop, but no difference.
This has just started happening.
II hoep you can see the screen print above.

It just means 1 or more couldn’t be removed not the whole section, I agree it’s confusing and the detail doesn’t differentiate between what is deleted and what is locked. I’ve added to my computer’s setup a “who lock this” style application to assess why ccleaner can’t clean x file or y file but that’s clicking on details hyperlinks over and over until i find one.
