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
Engine version: Godot Engine v4.2.2.stable.official (15073afe3856abd2aa1622492fe50026c7d63dc1)
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.
If removing the script doesn't stop it crashing then perhaps it was never the script's fault. Might be worth seeing if others have had your issue: https://github.com/godotengine/godot/issues
