Windows 10: Activated something, keys did weird things, now I can't type in my browser

This has happened multiple times before in the last 2 years:I play a game and all of a sudden it tabs me out and when I get back in, it keeps tabbing be out until I press a certain key no idea what key that is and then I can continue playing. But afterwards I can't type anything in my browser latest Firefox, not in the search bar, not in the url bar, not on a website - the letters simply don't appear. I can, however, type in e.g. Win 10's text editor and ctrl+c/ctrl+v. So far restarting my PC always reverted everything back to normal.This happened again just now: I was playing a Steam game

Possibly there can be the problem with Microsoft activation Server, so your Windows 10 is not activated. In this scenario, you need to wait and verify if it is the issue from Microsoft’s side. But if you are getting error code 0x803f7001, you can also try these steps:

1. Open Settings app. Then go to Update and security > Activation screen > Change product.
2. Type your Windows edition product key and click Next.
3. You’ll get We couldn’t activate Windows error message.
4. Retry steps 1-3 then type your 25-characters unique product key.
5. Wait for the process to complete, Windows 10 is activated.

Hope something helps this problem
