Block resolution and continue as unblocked (Form of mist vs cats guidance)

Hi

I couldn't find how to solve Form of Mist vs Cats Guidance so I ask on broader terms: What happens on block resolution of a "continue as unblocked" action. Does window still exists?

Many thanks on advance


Form of Mist

Protean Strike: dodge.
Superior Protean Strike: combat ends. After combat ends, if this vampire was blocked while performing an action, they can burn 1 blood to continue the action with +1 stealth as if unblocked, even if stealth is not yet needed. A vampire can play only one Form of Mist at superior each action.

Cats' Guidance

Animalism Only usable by a locked vampire who has blocked, after block resolution. Unlock this vampire.
Superior Animalism +1 intercept.

yes, you can use Cat's guidance to unlock.
