URP "Lit" sample is missing all shaders in WebGL build

same here
I tried to add the shader to “always included” but then i get this error:

Universal Render Pipeline/Lit has too many Shader variants(77309411328).To resolve this, go to Project Settings > Graphics and remove this Shader from the Always Included Shaders list.For more explicit control over how Unity includes specific Shader variants in a build, use a ShaderVariantCollection.
