Hi,

Here is an article which record a similar issue with you, please refer to it and check the measures on your side.

"Keyset does not exist" error message when you try to change the identity of an application pool by using Internet Information Services Manager from a remote computer

Some people solved the issue by following the steps below.

Open File Explorer and browse to this location:

C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC

Delete everything within that folder

If you can't delete everything within that folder due to an Administrator error, rename the folder.

Go to Settings-> Accounts->Sign-in Options

Click Add a PIN again and set your PIN
