error 10013

Hi!
I'm trying to run this code in Deno but the result is: Uncaught (in promise) PermissionDenied: An attempt was made to access a socket in a way forbidden by its access permissions. (os error 10013)

  import { serve } from "https://deno.land/std@0.150.0/http/server.ts";
  import { Server } from "https://deno.land/x/socket_io@0.1.1/mod.ts";

  const io = new Server();

  io.on("connection", (socket) => {
    console.log(`socket ${socket.id} connected`);

    socket.emit("hello", "world");

    socket.on("disconnect", (reason) => {
      console.log(`socket ${socket.id} disconnected due to ${reason}`);
    });
  });

  await serve(io.handler(), {
    port: 3000,
  });

And before that code I tried to run

   import { serve } from "https://deno.land/std@0.50.0/http/server.ts";
  
   const server = serve({ port: 8008 });
   console.log("http://localhost:8008/");
  
   for await (const req of server) {
   
    if (req.url === '/') {
    req.respond({
      status: 200,
      body: await Deno.open('./public/index.html')
   });
  }
    
  }

and it shows the same error. Is there any way to fix this or to run deno properly?
