Hello,
Good work on getting the headstart on the troubleshooting, that’s most everything done.
I looked up the error code and had several results of other forumposters having issues with third party antivirus programs, do you have any that you installed manually? You might want to disable those while you’re trying to login with your Microsoft account.
You also mentioned that the credential manager service is running, I’d like you to open credential manager itself and remove all accounts in there, open the start menu, search credentials manager, and delete any data in there, do note that this will cause you to have to login all over again as this deletes the data windows performs auto-logins with.
Hope this helps,
JC
