Windows 10: Unable to type on Start

I have been unable to type on Start or in any Windows search bars ie in Settings since yesterday. The keyboard otherwise is still functional, so I believe this is a PC problem. I looked up fixes and none of them seem to have solved this for me - one of them suggested running the ctfmon.exe application under C:\Windows\System32 however I would run into an error with the status 0xc0000020 and tried to look a solution for this error up to no avail.Any form of help or solution to any of these problems would be very much appreciated.

Unable to type text in any of start (search func)

• As mentioned in title, I was unable to type in the start (press start > press any key to search)
• Unable to type wifi password too (but can paste) > essentially the wifi passcode textbox that popups up from taskbar
• I have tried many well-known antiviruses, malwarebytes etc. but none could solve the issue
• I have also tried powershell scripts to fix but it doesn't work either:
  
  

 

Windows Defender disabled and is unable to start


OK. I am not sure if you can complete the steps below.......................
In the search box, type services.msc > Enter
Items in the Services box are listed alphabetically.
Scroll down to Windows Defender Service...........................
at Status heading, it should be.................................... Running
at Startup type, it should be......................................... Automatic







If that is not what yours said, right click at Windows Defender Service > click Properties >
can you change the Startup type to Automatic and Service status to Start ?
If yes, do so and click OK when done.
