Godot Blackscreen remote Debug Android

Godot Version

4.2.2

Hello, a couple of days ago this was still working like a charm. Since today I can install the game on Android but I get only a blackscreen on my phone after the Godot logo appears briefly.
I narrowed the problem down to be in the Game_Level Scene. When I add the “SpaceBackground” scene, which is a Parallax node, I get the blackscreen. If I delete it, the game is being displayed. Commenting out the code inside of SpaceBackground scene doesn´t work. Does somebody have an idea of what is going wrong here?

I´ve uploaded it here with my Android build folder:

If you want me to upload it somewhere else, please let me know, since I am an absolute beginner and have no experience with uploading projects.

I am using a Pixel 8 Pro as my mobile device.

Best regards,
James
