Luks passphrase

During update of ubuntu i mistankenly entered Y when i was asked
-Confirm the question “Do you wish to add a disk encryption to the TPM”

This means when booting now im asked
-Enter Luks Disk Unlock Key Passphrase
When booting and choosing default boot.

This i cannot get past, and i see the error i made when i choose Y at question 2 during system update (should have been N)

So my question now is, whats my next step? a fix, OS reinstall, factory reset?`

Any help much appreciated
