Issue: Godot crashes when node not found, and attempting to connect to a non existant signal
Labels: topic:editor,needs testing,crash

### Tested versions

v4.3.stable.official.77dcf97d8

### System information

Windows 10 - Godot 4.3 stable - Vulkan 1.3.280 - Forward+

### Issue description

My 2D project is experiencing a continuous crash on open, believed to be due to a corrupted scene. The crash occurs immediately upon opening the project.

### Steps to reproduce

1. Created custom resource to store `ProjectileData`
2. Created a custom `Projectile` which extended `CharacterBody2D`, which had `@export var stats: Resource` which was the `ProjectileData` above
3. Created a `PlayerBeam` which extended `Projectile`
4. Attempted to add a `Timer` node to the base `Projectile`, but encountered issues starting the `Timer` 
5. Removed the `Timer` node from `Projectile` and its connected signal functions
6. Added the `Timer` node to `PlayerBeam` instead
7. Attempted to create a new inherited scene from player_beam.tscn (`PlayerBeam`), which resulted in a crash

### Minimal reproduction project (MRP)

1. Open the project. 
2. Project should open normally
3. If you double click `player_beam.tscn` in the godot editor FileSystem, the project will promptly crash
4. Subsequent attempts to open the project will immediately crash
