Hello William,
Thank you for reaching out about the issue with setting up a PIN in Windows Hello I understand how frustrating it can be when the setup times out especially since another account on the same PC works fine. This usually happens due to a configuration or service issue rather than something you accidentally checked or unchecked.
One effective solution is to reset the Windows Hello and PIN setup components by clearing the NGC folder which stores PIN-related data. To do this sign in as an administrator, navigate to C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC and delete all contents of the folder. After that restart your PC and try setting up the PIN again. This forces Windows to recreate the necessary files and often resolves timeout problems.
Could you let me know if you are comfortable performing these steps or if you need guidance on accessing the NGC folder?
I hope this answer is helpful if you have further questions feel free to reply back
Regards,
Marcelo
