Hi there,
Try disabling PIN login for the Microsoft Account (Settings > Accounts > Sign in options > PIN).
This has worked for most of the users.
You can try to disable the password protection feature to fix the Windows 11 network sharing not working problem. Go to Start > Control Panel > Network and Sharing Center > Change advanced sharing settings. Scroll down to find the “Password protected sharing” option, and click Turn off password protected sharing.
