When it asks for my password, I enter password and I'm in. It does not need a PIN in the password field, it needs the password, and the password only.
This may also depend upon the following setting to be disabled, I'm not sure - but at any rate, I never allow it to be enabled.

Also, note I said you had to log in and then remove the PIN completely, reboot, and then you could set it up again.
You cannot set it up from the login screen as the TPM association is broken. You have to disable it inside settings, then reboot, enable TPM in UEFI, then enable Hello (PIN) and set it up.
