The newest version of 145.0.3800.58-1 of microsoft-edge-stable changes the repo to download further updates from to https://dl.google.com/linux/chrome/deb/ At the moment this fails for me because I don't have Google's public key installed. But I doubt the URL is correct in the first place.
I guess Microsoft copies the maintainer scripts from Google's Chrome and forgot to patch the repo URL.
Yeah, I would not use any software from that supplier if my employer did not force me to...
