Save your life. My vs has encountered an error.

Why? My vs has a problem.
I was about to modify our website recently, But now I find that my vs cannot create a web project.
Let me first talk about my creation method. Let's see if there are any errors. (Although I think it's quite right)
Choose "new"> "project"> "ASP. net web application "and then change the local in http: // local/webapplication1 to my own IP address (because our enterprise is a fixed IP address, and this problem still occurs if the IP address is not changed ), however, after the change, the alarm still says ".. net. 168. *. */webapplication1: No Web server is detected. Make sure that the Web server is installed and running ."
I have never encountered this kind of problem before. I used to create it on my computer.

We are waiting for help from all heroes. Thank you!

Note: I have used many solutions on the network. This includes entering commands, but my computer is not obedient and will not be created!

Note: this problem has been solved and a new problem has emerged! The Web server is not running asp1.1. How can this problem be solved.
Originally, IIS was not installed on this machine. Seasick. I am a pig head (this problem has been solved)

Nd, why is there a problem. HTTP/1.1 500 server error. What is the problem. In this case, I am about to crash.
