Just a short remark about having the browser profile creation fail when I activated the Widevine extension in the Brave browser. this prompted the brave browser to restart. afterwards the browser profile creation crashed when I saved it. Now I tried not restarting the brave browser after activating the Widevine extention. This seemed to work. When I entered editing mode on the newly created browser profile the extension was activated. Do not know if this is a Will test some more. Especially Widevine is contentious for example open.spotify.com does not seem to play protected content despite having widevine activated in Brave.
