Couldn't not access Ubuntu-20.04

Dear sir/Ma'am,

  My PC is running the Insider preview build channel with Microsoft windows version Dev (OS build 21390.2025). Since morning I am not able to access any virtual machine facilities associated with ubuntu 20.04. I checked window update, which shows windows 10 expiration and windows 11 couldn't be downloaded due to some hardware requirement issues (attached screenshot). Kindly look over the issue, and help me to use the services which were previously accessible to me as a user.
