It looks like the origin/center of your model is far from the center of mass. I imported the glb into blender and set the origin to the center of mass of the object, exported it again and it appears fine in a simple example project.
You are welcome and good luck with your game, looks interesting! Looking forward to seeing the 3D models in the game. To me it seemed like the origin was the issue, I don't know if blender and max handle that differently. Perhaps it's something else though if you don't do any origin changes in blender before export and that just works.
