[Jestus]

Tested versions

Issue description

I upgraded my project 4.3 -> 4.4. I worked through many of the initial issues, but one of my scenes will not open in editor.

However, I can load the scene in-game, but when loading the scene I get 403 errors like so:

This series of errors repeat until:

  <C++ Error>   TOO_MANY_ERRORS
  <C++ Source>  :-1

Looking at the migration documentation, I don't see anything listed that might cause this.
The only Physics change is a single one for SoftBody3D
https://docs.godotengine.org/en/4.4/tutorials/migrating/upgrading_to_godot_4.4.html

Is there any immediate idea of what might be happening? Note: this happens in recovery mode as well.

ALSO:

If I load another scene (in-game) after the above, I get the following issues:

  <C++ Source>  modules/godot_physics_2d/godot_physics_server_2d.cpp:996 @ body_test_motion()
  <Stack Trace> Player.gd:100 @ _physics_process()
E 0:11:34:719   body_set_state: Parameter "body" is null.
  <C++ Source>  modules/godot_physics_2d/godot_physics_server_2d.cpp:772 @ body_set_state()

This also repeats hundreds of times.

Steps to reproduce

Simply hit F5 to run the project, errors go bananas.

Reproduced on MacOs.

Godot Editor 4.4 freezes, even in recovery mode.
With Godot Editor 4.3 I can open the project within 20 seconds.
