Description

When creating a Curve Compression Setting asset and changing the codec from Compressed Rich Curves to either Uniform Indexable or Uniformly Sampled the editor crashes.

Tested in //UE4/Release-4.26 @ CL 15973114 and this did not occur, so marking as a Regression.

Steps to Reproduce
  1. Open any project
  2. Right-click in the content browser
  3. Select Animation > Curve Compression Setting
  4. Open the Curve Compression Setting asset
  5. Change the codec to either Uniform Indexable or Uniformly Sampled

RESULT:

The editor crashes

EXPECTED:

**The user can change the codec type without crashing
