Describe the bug
After PhysX Character Controller + PhysX Character Gameplay entity reaches ground, the gravity stops affecting it, even after the PhysX Character Gameplay Gravity Multiplier is modified. If the ground is moved from under the stationary PhysX Character Controller + PhysX Character Gameplay or a velocity is applied to it so that it leaves ground, the gravity will be applied as expected.

It should be noted that if the entity is blocked from above (so the bottom of the PhysX Character Controller is not on ground), it won't prevent the Gravity from being applied. Only while the entity is on ground can this issue be observed.

Assets required

• Following Script Canvas graph prepared:
  
• Entity with following components prepared:
  
  

Steps to reproduce

1. Place the entity created in the Assets required section slightly above the Ground entity, so that it rests before the Script Canvas Print is triggered (a message shows up in the Console).
2. Enter the Game Mode and observe the entity.

Expected behavior
After the message is printed to the Console, the entity starts ascending.

Actual behavior
Nothing happens, entity remains stationary.
