Hi simona,

I suspect you have enabled FileVault during an upgrade to Tahoe 26.
Check your macOS Settings -> Privacy & Security -> FileVault. If you intend to use external screen before login, this functionality must remain disabled.

PS. I've moved your message to a dedicated thread as it appears to be a unique problem.

Regards,
Szymon
