UE4-26 SimulatePhysics with Possess

Hello everyone,

in UE4-26,
First of all sorry for my bad english. I have a character with CharacterMovement. When i set SimulatePhysics = true. Character physics not working properly like first video.

But when I run these two codes together:
-SimulatePhysics = true
-controller->UnPossess()

The character physics works very well, as does the second video.

How i can use “SimulatePhysics=true” with Possess.
