How to fix these warnings?

I am getting these warnings for some reason just by pressing play. I don’t have any scripts or objects in the scene, so it’s a new project but I still get them.

Yellow warnings can be ignored in a final build and will still run despite the yellow warnings, red warnings you have to fix however. Without information of what your scene looks like or what your inspector has in it I cannot be of too much help.

however, if you copy and paste those warnings into your favorite search engine, it will usually lead you to the answer on how to resolve them. In face if you copy and paste those on here, maybe people with a similar issue in the future will know how to resolve them.
