Wampserver Too few arguments to function listen_ports()?

I have just installed wampserver64 (v: wampserver3.2.6_x64) on window10 and after running wampserver, the icon is green but not connecting to localhost.
The page took too much time to load and then gave a response

This site can’t be reached
The connection was reset.
Try:
Checking the connection
Checking the proxy and the firewall
Running Windows Network Diagnostics
ERR_CONNECTION_RESET

Then I tried just “localhost” in the search bar and it gave me the following error
enter image description here

Fatal error: Uncaught ArgumentCountError: Too few arguments to function listen_ports(), 0 passed in C:wamp64wwwindex.php on line 40 and exactly 1 expected in C:wamp64scriptswampserver.lib.php on line 529

Kindly help out me. I have changed port 80 to 8080 but the same error. Thanks!
