builing's errors

Hello!! I don’t know if this has something to do with it but hey, … I’m trying to build my unity project to play it from outside the program and send it to my friends to test it but they give me these errors, do you know how to fix them? Thank you

As the error says you are trying to build it to a directory that contains the VisualStudio project. Build the project to its own empty sub-directory.
