I didn’t make any changes in the project settings or something, but I did change some GDScript. After I did that, every time I open a different scene in the scene dock the Engine crashes. This right here is the backtrace:

================================================================
handle_crash: Program crashed with signal 11

Dumping the backtrace. Please include this when reporting the bug to the project developer.

================================================================

I can also share the project files if that would be useful (I plan on open-sourcing it either way). I am using Debain 12 (GNU/Linux) using Gnome. In the backtrace I used Godot 4.2.2, but until just now where the crashes set in, I was using the latest Godot 4.3 dev6 build. So these crashes don’t occur because of the dev builds.
