Crash after changing either the Anim Start or End times of an Animation Composite

Description

This is a regression tested in //UE4/Release-4.27 CL#18319896

Crash after changing either the Anim Start or End times of an Animation Composite when using Enter to confirm their value.

Steps to Reproduce
  1. Create a new Third Person template
  2. In the content browser create a new Animation Composite using the SK_Mannequin_Skeleton
  3. In the Animation Composite drag and drop Jog_Fwd into the Composite track
  4. Select Jog_Fwd in the Composite Track
  5. In the Details panel for either Anim Start Time or Anim End Time enter a new value then press Enter to confirm the new value
  6. Jog_Fwd is deselected and the Details panel is blank
  7. Reselect Jog_Fwd

Expected Results:
Jog_fwd details is opened and the changes to start or end time are preserved.

Actual Results:
The editor crashes with a Fatal Error:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0xffffffffffffffff
Callstack

 

=== Critical error: ===

Fatal error!
