Bug Shader Graph not opening imported shadergraph files anymore (URP 7.3) (screenshots)

Hi, I have many shader graph files in my project which are still working, however one time when I went to open a shader graph file that had an error windows asked me what program I wanted to use to open the file? I dont remember what I hit, I think it chose Visual studio as default. Then I noticed I could no longer open the shader in shader graph, I just get a gray screen after I click on the open shader editor button. When I add new shadergraph files into my project now, they all have this problem. In the screenshot I attached you can see the shadergraph file I imported (icon is a white sheet) compared to an unlit graph I created myself.
