Why HDRP Lit using Stencil has no lighting?

I’ve been trying to create a wound shader to put on top of my characters head. Using a Custom pass I’ve first used a WriteMask to mask the head pixels and now I’m trying to apply a Lit Shader over it but for some reason this is the result I get:

It’s just an unmodified HDRP Lit Material with a green surface colour but for some reason it has no lighting regardless of culling Front or Back.

Also for extra info this is what it looks like with a Unlit Shader:

So after changing the Pass from ForwardOnly to ‘Forward’ I have gotten a much better result, but mind you with a new issue now; flickering. I’ve attached a GIF of the issue. I feel like I’m so close to getting stencils to work on a HDRP Lit - which has been a way bigger hassle than I ever anticipated.

Shader Tags used in writeMask Shader:

DepthOnlyShaderTags = new ShaderTagId[]
        {
            new ShaderTagId("DepthOnly"),
            new ShaderTagId("DepthForwardOnly"),
        };

Shader Tags Used in Lit Shader Pass:

shaderTagsLit = new ShaderTagId[]
        {
            new ShaderTagId("Forward"),
            new ShaderTagId("ForwardOnly"),
            new ShaderTagId("SRPDefaultUnlit"),
            new ShaderTagId("MotionVectors"),
            new ShaderTagId("GBuffer"),
        };

It’s to also be noted that the flickering persists even if providing no override Material.
