Same thing happening to me.
The passwords that are being cleared are in "Windows Credentials Manager - Web Credentials" - not the cookie-based ones.
Done some testing and CCleaner seems to be confusing Edge and IE11. Screenshot below shows IE11 completely de-selected and it still deletes saved passwords in IE11.
If I want to keep my IE11 passwords I have to set both Edge and IE11 to keep passwords.
This is a PITA as I have (well, had) many saved passwords.
Running Windows 10 64 Pro with all cumulative updates (no preview builds).
This seems to have started with the very latest CCleaner update 5.10.5373
Been using CCleaner for many years and highly recommend it to colleagues and friends.
A fix for this would be appreciated.
