Problem with writing in Windows Settings and in the Menu (example searching for Applications)

Hello,

I have the Problem with Windows 11, that I cant write anything into the Menu where you search for applications. I have the same problem in the settings, so I cant search for settings or anything releated to the Windows 11 Settings. I searched for that problem, but I could find an answer. I also tried to exit the Windows DEV channel, but I couldn't do it. Windows cant find, that im registred in the DEV channel.

Can someone help me?

Would be very nice.

Thanks in advance
