Windows 10: Windows can't be activated after update 20H2

I had a valid Windows License education pro.After I updated my Windows version to 20H2 I have the problem that my copy of Windows can't be activated.The error message says that I must be sure I am connected to the internet and I have to try later again. How is it possible that my license is gone after a Windows update?

Update 20h2

Hi Wicki,

20H2 should not be installed right-away on your device - MS said the rollout is only to a fraction of users and would be labeled as an optional update initially. Are you enrolled in WIP?

You may uninstall 20H2 using the steps below:

Update History is not showing v.20H2

Hi Dominic

I am Dave, an Independent Advisor, I will help you with this . . .

This is normal behavior in Windows 10, typically when you install a Feature Update like 20h2, the update history is wiped, this is to prevent the user from trying to uninstall an update that was prior to the Feature Update, which would de-stabilize Windows
10, the list should start building again, when some updates are applied to version 20h2 . . .
