Hi Greg, This is Ramesh,
This can happen if an incorrect keyboard layout/language (en-US vs en-UK) is selected in WinRE and your password contains the # symbol or other special characters.
To verify if the layout is the problem, please create a new local admin account and assign a password to it (without containing any special characters).
To create a new local admin account, open admin Command Prompt and run these commands:
net user user1 pass1 /add
net localgroup administrators user1 /add
(Note: Replace the placeholder text "user1" and "pass1" with the new user name and password, respectively.)
See if you can select the newly created admin account in WinRE and log in.
