Issue authentication wireless client using NPS

Hi

I have a working 802.1X wireless NPS setup but after upgrading one of the clients to Windows 10 1909 when trying to authenticate I get domain\Guest instead of the actual AD user in the event viewer. Obviously the client cannot authenticate. The user is logged in with his AD account. Other clients can authenticate on the same AP so the issue is related to that particular client. Any ideas?

Thank you
