Physics Constraint not working with Chaos Physics in compiled engine

I am trying to set up a physics constraint between two actors in a scene. I got it working in UE 4.25.3 and got a cube swinging like so:

However, I downloaded the release branch of the UE4 Github and compiled it with the chaos destruction system. I followed the tutorial for chaos compilation except for changing one line where the overview says to write the following in UE4Editor.Target.cs:

BuildEnvironment = TargetBuildEnvironment.Unique;

Due to Unreal crashing due to shaders not loading in the right order, I changed the above line to:

BuildEnvironment = TargetBuildEnvironment.Shared;

I created a copy of my project and opened it up and now I get the following:

I’m stumped as to why this happens as all the variables and settings are the same. I even wondered if there were changes to the engine with chaos physics but it all seemed identical. I would really appreciate any help.
