Godot 4.3 Beta Crash Bug - Advanced Signals in Editor

[squidodactyl]

Tested versions

Reproducible in: 4.3 dev 6, NOT reproducible in: v4.1.3.stable.official [f06b6836a]

System information

Windows 10, MSI Laptop, 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz 2.30 GHz, 16GB Ram, NVIDIA GeForce RTX 3070 Laptop GPU

Issue description

When trying to connect a signal to a script in the scene tree (in the example image: connecting the "pressed" signal of "button" to the parent nodes script), the signal properties popup window appears, however, when pressing the "advanced" button (to access advanced signal properties within the popup window), Godot will crash. Even bigger issue however! is that when reloading the project, trying to open any signal menu (by trying to connect a new signal: from anywhere, to anywhere) Godot will again crash, making the project unable to connect any new signals via the editor

Steps to reproduce

1. Have a scene tree with at least one node containing a script, example: A single "control" node with a blank script attached
2. Create a child "button" node
3. In the editor, go to the "button", and try connect a signal from the "Signals and Groups" tab
4. with the signal popup window now opened, press the sliding button named "advanced", towards the bottom of the popup window
5. Godot crashes
6. Restart Godot and reload the same project
7. attempt to open the signal popup window again via the "Signals and Groups" tab
8. Godot crashes as soon as the popup window opens, preventing the ability to connect signals via the editor
9. Sadness
