Thank you for the data.
Does the issue happen when using original Edge browser or only with Chromium-based Edge?
Irrespective of which Edge browser you're using, some of Kaspersky's utilities do not work with Edge - there are bug requests raised & under investigation with KLAB.
Specific to the certificate issue, if the issue exists when using original Edge browser please let us know?
If it's only with Chromium-based Edge, (that, as Superssjdan, correctly advised, is a beta release), we'll have to wait for Edge Chromium to be officially released & retest the certificate issue.
