Shader Graph is just completely pink

well i was trying to make a shader for my project with Shader Graph, but it was just pink no matter what colors i put in the 'Base Color' node, so i then followed what this forum indicates: https://forum.unity.com/threads/my-shader-graph-material-is-pink.529222/
but all of the things went pink, even the things that don'thave a material at all, this happens to me every time i convert them to URP however switching the shader to standart fixed it, but now nothing happens in any case
Thanks for Everyone giving support

 

i made a sprite lit shader(the only that seemed to work normally) but now instead of burning pink is invisible, in both sprites, but is pink in the normal lit & unlit shaders.
