I can't launch UE4.23 preview 4


I followed these steps (How to enable Chaos - Announcements - Unreal Engine Forums) to try Chaos in 4.23, but I encountered LOTS of errors at compilation or when trying to run the engine.
I solved most of them, but I am now blocked on a new error happening when I’m trying to launch the engine (after ~60% of the launch). The engine is triggering a break point… Watch the screenshot.

According to the file HoloLensAR.uplugin, the plugin is already disabled/uninstalled, so I don’t know why I am getting this error when I try to launch the engine.

I found how to create a Geometry Collection with Preview 4. It seems the interface changed between Preview 1 & 4.

So this is how I found the Chaos menu :


And this is how I created a Geometry Collection from the meshes I selected in the viewport :

I managed to solve this problem by simply changing my UE4Editor.Target.cs :

I replaced
BuildEnvironment = TargetBuildEnvironment.Unique;
BuildEnvironment = TargetBuildEnvironment.Shared;

but now I can’t see the button to create a geometry collection…
