Not just me then, I'm on the Swedish language version of W11. I don't even have a insider build (I don't think at least), but yesterday out of nowhere, widgets or the msedgewebview2.exe started idling at 8% cpu. all widgets are disabled, teams is uninstalled and I do not use Edge as a browser.
and yeah, have to end the task from the task manager to make the cpu hogging stop.
