CCleaner uninstalled by Windows 11 after last Windows update for security reasons

Running CCleaner with Windows 11 and yesterday , after last Windows update CCleaner disappeared without any notice. After a short investigation I found out it was due to security reasons.
Anyone had same experience ? Any suggestion?
Thanks

No sign of that here.

CCleaner can access the Windows System (to clean system files) and sometimes Windows Defender and other AVs have issues with new CC versions, simply because it’s a new version, and it can take them a while to catch up that it’s been changed.

I would simply try reinstalling CCleaner, you can download an installer from here: Download CCleaner builds | CCleaner Portable, Slim, and more

Thank you, will re install.
