The danger Sculk Sensor bug of sensoring

This is a very serious issues. The Sculk Sensor will not attract while you are sneaking, right? In every time when I quit out and come back. I wasn't sneaking, the sensor will not attract while I didn't move. However, this time when I come back. I swear I didn't fall down, drop something or moving... I quit the game every time was sneaking and come back was "Standing"! This time the sensor was caught me because of "stand landing" on a "non-wool" block. I swear I didn't  falling that time! The "Sculk Shrieker" attract in meantime. It was too danger when I everytime come back if it doesn't fix it.
