Windows Sign In Screen Asking for Email or Phone Number - Cannot Autologin to Domain Credentials

Question

We have several PCs on site that are set via group policy to automatically log in to a specific account. However, a few PCs are running into issues signing in, and never seem to automatically sign in on boot. I've checked group policy and verified the entries exist locally at one of the machines that's running into this issue. I've noticed a potential problem is that the Windows login screen appears to be different to most PCs on the domain as it's asking for an email or phone number instead of domain credentials. How can I force the PC to boot to the domain login screen?
