Hey Anil pls let us know what Operating System you are using, problems differ for Linux and Windows .
One common solution can be checking port for services. As in Xampp we have different port for running different services.
Some ports are default and shared by many applications. But when we run the application when one is already running , it gives block port warning. So try changing ports for services one by one and checking which port is blocked.
If more issues just share error text here…
