Windows Hello error 0x801c004d

Hi

I am unable to enroll by laptop to use a PIN for login.

I receive this error, 0x801c004d. This error is not listed on Microsoft's site.

I have enable pin login, taken ownership of the ngc folder. Including several other options. The issue persists.

Any ideas?

Thank you
