Camera Glitch After Blender Simple Plane Map Import

Godot Version

Godot 4.0

Question

Using Blender 3.0.0 to Export a Simple Plane Map, with nothing except the simple plane itself, a Separate .gltf file, no textures - first around 3000m, then around 600m [tried it with smaller size, no change to the glitch]

So the Glitch is: After the Map is Imported into Godot, and I run the scene, with just a Player Cube, Nothing More, A player cube from Godot itself - and a Camera to view the Scene, and a Directional Light - Well, there is this Glitch, where the Player Movement Controls [Even using the Default Movement Script for the CharacterBody3D] - The Player Movement Controls are Transferred into the Camera itself - nothing else has a script except the Player - The Camera has No Script.

So now I can only move from within the camera, as if I were the camera, and the only Movement the Player can make is Jump.

I’ve tried a lot of things, a lot of debugging.

Nothing worked.

So I can move up, left, right, down with the Camera Itself.

Watching the Player Jump - if I press the spacebar.

If I remove all Blender Files - the Glitch remains.

Only until I create a Project from Scratch, creating a Map from within Godot, with a simple Cube, and run the scene, can I go back to moving as the Player, and the Camera remains Static.

This is my Welcome to Godot.

Please help, before I switch engines.

I love Godot, but what a Welcome this has been.

What does your scene tree look like?
