Internal Script Error: Opcode 0 (Please report) when using CACHE_MODE_IGNORE_DEEP with ResourceLoader.load()

### Tested versions

Godot version: 4.3.stable

### System information

Godot v4.3.stable - Windows 10.0.26100 - GLES3 (Compatibility) - NVIDIA GeForce RTX 3060 (NVIDIA; 32.0.15.6636) - 12th Gen Intel(R) Core(TM) i7-12700F (20 Threads)

### Issue description

Got an internal script error Opcode 0 and it is requested that I report it so I'm reporting it. Here's the image.


### Steps to reproduce

Use ResourceLoader.load(..., CACHE_MODE_IGNORE_DEEP) to load the same Resource at least twice.

Update: it appears to be related to the cach_mode I was using with ResourceLoader. Loading the resource a second time causes the issue. My understanding is that my use case should be valid but correct me if I misunderstood.

Start with the attached opcode-0-bug.zip reproduction and the ResourceLoader.load() call using CACHE_MODE_IGNORE_DEEP. Reproduce loading the same resource at least twice, then trace the cache-mode handling in the Godot engine. Done means the repeated load no longer produces the internal Opcode 0 error.
