Issue: Godot 4.3 Crashes During Import of Large Asset Directory
Labels: bug,topic:editor,confirmed,needs testing,crash

### Tested versions

Reproducible in Godot Engine v4.3.stable.flathub.77dcf97d8. This also occurs on the 4.3 Steam release as well. This did not occur in the 4.2.1 release.

EDIT: It does occur in the 4.2.2 release on Steam, but instead of crashing, it becomes unresponsive while maxing my CPU cores. I let it run for 25 minutes, and it was still unresponsive. This is on an AMD 5800X3D, so it's unlikely that I killed it too soon.

### System information

MX Linux 23.3 6.9.12-2-liquorix-amd64 

### Issue description

Importing a large directory of assets causes a crash when the editor attempts to import and index them. To give an idea:
79926 items (76209 files, 3716 folders)
643.0 MiB (674,255,333 bytes)

I get the following output from the terminal running it with the --verbose flag:

It also keeps the focus of my terminal emulator despite the process having completely crashed and no longer having a PID. I have to CTRL+C to escape it.

### Steps to reproduce

1. This is a real simple one. Create a new project with a new directory.
2. Copy the assets to the root of the directory.
3. Select the //res folder to initiate the import.
4. Wait for the crash to happen.

I have put a download of a 7zip archive of the asset directory that causes the crash in the MRP.

### Minimal reproduction project (MRP)

Please only download this if you are actually working on the troubleshooting, I have limited bandwidth allotment for this.
