Issue description

Creating an RDShaderSpirV object in C# causes a crash.

This is a regression from beta 15, presumably related to the C# renames. The issue does not occur in GDScript.

Steps to reproduce

Create a C# RDShaderSpirV object by using RenderingDevice.ShaderCompileSpirVFromSource or ResourceLoader.Load (with a SPIR-V bytecode resource).

The attached MRP is just:

        RenderingDevice rd = RenderingServer.GetRenderingDevice();
        using var spirv = rd.ShaderCompileSpirVFromSource(new RDShaderSource());

Did you remove the .godot/mono folder before opening the project in the new beta?

Did you remove the .godot/mono folder before opening the project in the new beta?

Yes. The MRP was created from scratch in beta 16, and I also cleared out the GodotNuGetFallbackFolder.

I am getting the same error message thrown but when trying to execute this line of code: player.audio.Stream = ResourceLoader.Load<AudioStream>("res://asset/audio/whoosh.wav");
The error message is:
Godot.NativeInterop.NativeFuncs.generated.cs:129 @ IntPtr Godot.NativeInterop.NativeFuncs.godotsharp_internal_unmanaged_get_instance_binding_managed(IntPtr ): Parameter "strong_gchandle.value" is null.
