A Bing service that gives you enhanced search details from billions of web documents.
It seems that the bing discover option (sidebar) is causing the issue. Deactivation did not solve the issue but starting Edge with the msUndersideButton feature disabled works for me. I simple created a new Edge link on the desktop with target: "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" -disable-features=msUndersideButton" . Now the bing discovery doesn't get called. Will wait and try to reenable the feature later after some update cycles.
