CCleaner Browser suddenly very slow

Since yesterday, I have fiber optics for my home internet connection.

Since then, all my browsers are much faster, but CCleaner Browser is so slow, that it is almost not usable any more.

I already reinstalled, but the problem remains.

See attachments for the speedtest on Chrome and on CCleaner.

CCleaner is still looking for a final solution.

CCleaner is still searching for a conclusive answer.
