Description

This is a regression. Tested in //UE5/Release-5.2 CL26001984

Opening the FP_Walk_Fwd animation in the first person template results in an assertion.

Steps to Reproduce
  1. Create a new First Person Template project
  2. In the Content Browser search for FP_Walk_Fwd
  3. Double click the asset to open it

Expected Results:
The animation opens in a new window.

Actual Results:
The editor crashes with an Assertion.
