Crypt's Sons, Lock and Obedience

Two questions about Crypt's Sons from V5 for Vendetta tournament yesterday. In both instances Player A's anarch vampire with Crypt's Sons is acting, Player B's vampire is unlocked and blocking:

1. Player B blocks successfully. Player A uses Crypt's Sons ability to cancel combat. Is the blocking vampire locked?

2. Player B blocks successfully. Does he get to play Obedience before Player A can use the Crypt's Sons ability? Or does Player A get the opportunity to use the Crypt's Sons effect first as the acting player? If it is the latter, is the blocking vampire locked?

I think both questions are linked because at the core of it it's about the ability's timing. Can it be played as a before combat/resolution effect like Obedience? (But in that case the blocking vampire surely should stay unlocked? It was my understanding Obedience parenthesis text was just a reminder.) Or is it played during combat like superior Form of Mist (but in that case, Player B should get the opportunity to play Obedience before the ability). Or does the acting Methusalah get to choose? I'm a bit puzzled ☺︎

My answers are based on www.vekn.net/forum/rules-questions/77667-what-exactly-is-block-resolution this topic. So I assume... Lock+enter combat happens simultaneously as a part of successfull Block resolution. In the 1st case combat cancelled, and blocking minion should stay unlocked.
In the 2nd case acting minion have a priority to play cards/activate abilities, so he always activates crypt's sons first until he decides to enter combat.

Thanks for asking Lip,i planed to ask too.
yesterday during tournament i ask Ankha in discord what happen,so him answer:

acting first => Crypt's Sons first
so reacting vampire lock
A burn blood to continue
and obedience cannot be played

Probably Ankha confirm later when see topic

Yes. Crypt's Son cancels the combat, but the lock part takes place.

The acting player always get the opportunity to play their effects first.
So A uses Crypt's Sons, the blocking vampire B is locked and the action continues. B cannot play Obedience since B is not about to enter combat (combat was canceled by Crypt's Sons).

What about Mental Maze, which is played before block resolution? Can MM be played before the acting player has the chance to burn a blood from Crypt's Sons?
