Unity ASW URP Fork doesn't work with RenderTextures / Lit Shader

[baggyg]

I'm using the Meta URP fork for ASW support (Unity 2022.3). I also have functionality in my game for taking an instant photo onto a RenderTexture. However when I do this the images I get seem to be showing the motion vectors and nothing else. 

Its definitely due to the fork as identical setup (Vulkan / Standalone build) worked perfectly before the switch over. PCVR / DX11 works fine either way. 

Is there any way to strip the motion data out of these or a way to force that particular camera to not do the motion vector pass?

Sorry for repeat convo (put in the wrong board to start with)
