for EasyEventEditor.cs:262 I had to modify to:
if (enableOverride && drawerTypeMap!=null && drawerTypeMap.FieldType!=null)
on a fresh install (Version that came with the current VRCSDK). It was constantly throwing a NullObjectException on 264 and breaks the 3D view for editor.
I know this is UdonSharp, but it still happened only in the current SDK (Worlds-3.6.1)
