My Material is pink after applying texture, how do I fix it?

I saw some similiar question as mine but could not find an answer that works. I am making a 2d game using the urp. I tried to apply a texture I found here

on on of my square sprites but what I got in result was a pink texture. I tried fixiing it by changing the shader from standard to universal render pipline > 2d> and all the options there but nothing worked. If you know how to fix it, it would be much appreciated. Btw, I am new with game dev so sorry if I missed something simple. Thank you
