Fatal Error: EXCEPTION_ACCESS_VIOLATION_READ / 0xffffffffffffffff - 6422761733 : crashes/222bea44-f9b1-4948-5ebf-cb10e739fd36

Crash happened when doing a shader hot reload.
I was following the Shader tutorials and wanted to try out attributes.
When i take out 'Default4(1, 0, 0, 1)' the project opens normally again.

I run on a Windows 10 Host.
DotNet Version: 10.0.301

test.shader:
'HEADER

{

    Description = "My First Shader";

}

MODES

{

    Forward();

    Depth();

}

FEATURES

{

    #include "common/features.hlsl"

}

COMMON

{

    #include "common/shared.hlsl"

}

struct VertexInput

{

    #include "common/vertexinput.hlsl"

};

struct PixelInput

{

    #include "common/pixelinput.hlsl"

};

VS

{

    #include "common/vertex.hlsl"

    PixelInput MainVs( VertexInput i )

    {

        PixelInput o = ProcessVertex( i );

        return FinalizeVertex( o );

    }

}

PS

{

    #include "common/pixel.hlsl"

    float4 color < UiType(Color); Default4(1, 0, 0, 1) >;

    float4 MainPs( PixelInput i ) : SV_Target0

    {

        float r = 0;

        float g = 0;

        if ( i.vTextureCoords.x < 0.5 )

            r = 1;

        if ( i.vTextureCoords.y < 0.5 )

            g = 1;

        return color;

        //return float4( r, g, 0, 1 ); // Red

        //return float4(lerp(0, 1, i.vTextureCoords.x), lerp(0, 1, i.vTextureCoords.y), 0, 1); // Gradient

    }

}'

basic throwaway Component:
'using Sandbox;

public sealed class MyComponent : Component

{

    Color color = new Color( 1, 0, 0, 1 );

    ModelRenderer renderer;

    protected override void OnStart()

    {

        renderer = GameObject.Components.GetOrCreate<ModelRenderer>();

    }

    protected override void OnUpdate()

    {

        color += new Color( 0, 1f * Time.Delta, 0, 0 );

        if ( color.g > 1 )

        {

            color.g = 0;

        }

        renderer.Attributes.Set( "Color", color );

    }

}'

The project keeps crashing even during the editor bootup sequence as soon as it's trying to compile the shaders.

The error apparently was that "Default4" expecting float values instead of integers.
Changing the values from ex. '0' -> '0.0' fixed it.

CreateTexture2D biden blasts my project

i think its ram issue but idk
