UdonSharp or any UdonSharp prefab breaks the World SDK

I want to create this topic because as said in the title, UdonSharp or any UdonSharp prefab breaks the World SDK.

I don’t understand why it happened. The only thing I did is imported the latest version of the World SDK, while I have UdonSharp in my project.

The control panel is fine, but I can’t test or publish/update one of my worlds. If I reopen my World SDK project, the control panel is gone in the dropdown menu.

This is the old screenshot I have taken. This shows what it looks like if I import UdonSharp or any UdonSharp prefabs. Is there any way I can fix the UdonSharp issue?

Check the Unity Console for errors.

I’ve imported UdonSharp, along with some UdonSharp prefabs. When I tested the world with the UdonSharp prefabs being in the scene, it worked.
