Only fix that worked for me was a windows reinstall. Sucks, but of all the things I tried, that's the only thing that worked.
I re-installed my windows 11 twice now and even did a factory reset to my router. still no luck.
tried several approaches and searched reddit, several websites and the microsoft answers forum but couldn't find anything that helped.
