Test another machine to make sure the keyboard is OK if it’s OK when you have a windows problem. You can start by running the windows troubleshooter

Thanks for answering.
Troubleshooter didn't find anything and it's not a hardware problem.
The problem was a microsoft update KB44807320, around 300 kb.
Unistalled and everything is fine.
