Game Window & Editor Crash in 4.7dev1 & 4.7dev2

[noahgree]

Tested versions

• Reproducible in 4.7dev1, 4.7dev2
• Not reproducible in 4.6, 4.6.2rc1

System information

Godot v4.7.dev2 - macOS Tahoe (26.3.1) - Multi-window, 2 monitors - Metal (Forward+) - integrated Apple M2 Max (Apple8) - Apple M2 Max (12 threads) - 32.00 GiB memory

Issue description

I cannot figure out what triggers the game window crash, but as of 4.7 the game window crashes with no output in editor console after doing certain actions. I actually narrowed it down to a few candidates, and upon opening one of the scripts for one of my weapon scenes, the entire editor crashed, not just the game. This script is a tool script, though. Now I can't open the project at all on 4.7. I was able to record the logs from my Mac's system console when the game window crashed and have pasted below:

Steps to reproduce

I cannot figure this out exactly. Hopefully the logs help.

Minimal reproduction project (MRP)

None outside of my personal project, although I'll note that my project is in GDScript. I haven't been able to recreate this in a new project.

Fixed in 4.7 dev 3. Thanks for all the hard work!
