Latency problems after win11(23H) update to win11(25H)

Hots worked just fine under windows 11 ver.23H. After the last windows update to win11ver.25H the gameplay is very buggy. In the main screen you can click a button and 5 seconds later it will respond. In game its like you watch a powerpoint presentation, completely not playable. All my other games from Steam and Epic worked normally with the windows 25H version.
I did a clean install with all the Battlenet games and the Battlenet app.
I updated all my hardware drivers including my GPU (RTX3060) and the latency problem remains. I completed all the help from the technical forum but nothing solved the problem. Then at last i went back with the windows build in GoBack function to win11 version 23H. After that everything worked just fine as before. Has someone had this problem also? What did I missed?
