It makes sense because Enemy Dead State should only ever deactivate the SpriteRenderer if you wish so.

Solution 1

From here, check if EnemyDead animation is set to loop. If it is - uncheck it. It should not be looping.

Solution 2

Separate into two states:

• EnemyDying (dying animation (let's say 4 frames))
• EnemyDead (just SpriteRenderer set to false (should not be looping))

AnyState -> EnemyDying -> EnemyDead (Has Exit Time = true)
