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.
The editor crashes
**The user can change the codec type without crashing
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-135507 in the post.
