PD 20 - Windows 11 auto-login disabled and duplicate sign-in tiles

I'm running Parallels Desktop 20 on a MacBook with Touch ID and macOS Sonoma. Before upgrading, my Windows 11 Pro Insider VM signed in automatically: Parallels stored the Windows password in the macOS Keychain, prompted for Touch ID, and then completed the logon without user interaction. After the upgrade the logon screen now shows two tiles for the same account--one generic and one branded "Parallels Touch ID". Touch ID still unlocks the branded tile, but Windows never signs in automatically.

What I've tried so far: reinstalled Parallels Tools and performed a first manual logon to rebuild the Keychain entry; removed any old Keychain passwords and let Parallels create a new one; enabled autologin with prlctl set --autologin on --userpasswd; turned off the "Windows Hello only" requirement in Settings and reset the password-less registry flag; ran netplwiz (the "require password" box is hidden on this Insider build); created an "Exclude Credential Providers" policy through both Group Policy and the registry; and even attempted to disable the native password providers from an elevated prompt and from a SYSTEM prompt. None of these steps removed the duplicate tile or restored the original auto-login behavior.

Touch ID itself works, but I can't get Windows to sign in automatically as it did before. Any suggestions to hide the extra tile or re-enable the full Parallels + Keychain auto-login flow would be appreciated.
