Change the shader to standard

in unity 2020, to fix it, try using Universal render pipeline shader ( or HDRP ) depending the render pipelines you’re using

This happened to me recently. I am using URP. Long story short, I started a project on my main computer. I pushed it up to github so I could work on it on a secondary computer. On that second computer, I had to install a newer version of unity editor. I then I pushed the project again and got back on my first computer. I had the first computer still open the project as I pulled the latest commit. Unfortunately, the editor version was now out of date on my first computer. I installed the same version as the secondary computer and made sure to restart unity and everything worked.
