This is not a regression. Tested in //UE5/Release-5.0 CL20979098
The array for Vector Parameters isn't getting populated when called from a Dynamic Material Instance.
The length of the array is equal to the number of Vector Parameters in the Material.
The length returns 0. The array isn't populated.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-173218 in the post.
