Hello guys and search for a solution for this problem and its was the simple of things.
I don´t know why it works but try it and tell if it works for you guys too.
- Press Win + R (to open Run )
- copy paste and press enter to run this program. "C:\Windows\system32\ctfmon.exe". it brings back the language bar and for me it allowed me to type in windows search, start menu and WINDOWS 10 apps again
I think it is due to missing Language bar or some think like that.
But when you restart it may stopped working again, just create a task to run this program every time you start the windows and your good to go.
Best regards.
