why this simple shader crashes the game?

i got a very simple shader, when i run my game with it, it instantly crashes.

the shader:

shader TileMapShader<Texture2D TTexture>: Texturing, ComputeColor
{
    compose ComputeColor albedoTexture;
    override float4 Compute()
    {        
        return TTexture.Sample(Texturing.Sampler, float2(0.5f,0.5f));
    }    
};

both textures are set (the generic one and the composed one):

this is the log from my machine:

System.AggregateException: One or more errors occurred. (Could not compile shader. See error messages.[(1,1)]: Error:  E0237: The variable [Material] in class [TileMapShader_Min1691143736] is not defined

and the one from another person on discord that tried the sahder for me on his machine in his project just for test porpuse:

```

Start by reproducing the TileMapShader example with the reported texture and mixin setup, then inspect the shader-compilation path in Stride.Rendering.EffectSystem.cs and the render preparation path in RootEffectRenderFeature.cs. Compare the reported E0237/E0238 diagnostics and NullReferenceException across both repros; done means the shader failure is handled without crashing and the resulting error identifies the invalid setup.
