[mac] Godot Editor Stops Responding When Trying to Save & Close After Moving Project Location

### Tested versions

v4.2.1.stable.official [b09f793f5]

### System information

Mac 14.2.1 (23C71) - Apple M1 Max

### Issue description

When editing a Godot project and moving the project folder outside the editor (ex: rename the root project folder), attempting to save-and-quit results in an unresponsive app that I need to force-quit to close.

### Steps to reproduce

1. Create a project
2. Confirm project in file location
3. Edit project
a. Change something in project so a save will need to trigger when trying to close
4. In terminal, change the project folder to new name (ex: `test` -> `test_changed`)
5. From the Godot editor, hit Cmd + Q to initiate a close
6. Click `Save & Close`
7. Observe beachball of death as the application stops responding

Side note: I have been able to reproduce this a few times, but once it had a pop-up saying that the project had moved, but upon clicking `Ok` button, the same unresponsiveness happened

### Minimal reproduction project (MRP)

Works on any newly created project from (I tested on 4.2.1 and it had the same behavior regardless of render type)

[test.zip](https://github.com/godotengine/godot/files/14002782/test.zip)

No source file, test, or entry point is named. Start by reproducing the issue with a newly created project, rename its folder externally, then use Cmd + Q and Save & Close. Done means the Godot editor remains responsive and closes successfully after the project location changes.
