I am trying to figure out if an extra attack can be interrupted by another effect and terminate the attack action before all attacks are completed.
The specific example I'm dealing with is thus:
I have a fighter with Riposte and the Crusher feat. Enemy fighter takes an attack action to swing at me with extra attack. Let's say 3 attacks just to put a number on it.
First attack hits, I take damage.
Second attack MISSES. Here's where I need the clarification.
First, can I react with Riposte to attack before the enemy's third attack of the action?
Second, if so, if I hit and the Crusher feat triggers to move the enemy out of range, would that then negate the enemies third attack?
And third, is there any relevant difference in this scenario between the extra attack feature and the multiattack ability?
Did some googling and I think it should work and the third attack should be wasted but could not confirm as I saw opinions both ways.

Your Riposte attack triggers immediately after the second attack misses, but Crusher will not prevent a third attack.
The Riposte maneuver states:
The rules for reactions state:
Since the trigger is the second attack missing, your reaction to make a melee attack occurs once the second attack misses, which is before the enemy makes a third attack, since the enemy resumes its turn once your reaction is resolved.
Now, the Crusher feat states:
All this does is move the target five feet away. It does not prevent the enemy from moving back into range and hitting you with the third attack, since the rules for "Moving Between Attacks" state:
So Crusher will only prevent a third melee attack from the enemy if the enemy has 0 movement remaining for the turn, and does not have a Reach weapon, though it still would not prevent them from getting angry and throwing their sword at you. The above rule applies the same way to a monster or NPC with the Multiattack action.
