Description

Engine crashes when creating a new pose asset in persona using the Create Asset option
-Tested with walk, idle, and run anims
-Didn't crash only once out of the several times tested with the ThirdPerson_Jump anim/seems consistent otherwise

Steps to Reproduce
  1. Create a Third Person template project
  2. Open the ThirdPersonIdle animation
  3. Pause the animation
  4. Create Asset < Create Pose Asset < Current Pose
  5. The Window for Create a New Animation Assets will open
  6. Select OK(Don't need to change the name)
  7. Observe crash

Expected: Engine does not crash when creating a new pose asset through persona
Result: Engine crashes when creating a new pose asset through persona
