Solution for cypress failed to make a connection to the Chrome DevTools Protocol

Hello,
I need solution for cypress failed to make a connection to the Chrome DevTools Protocol in cypress

Hi,
Did you check the state of the port the error indicates? I would guess the port is used by another process.

Okay I will check thanks for replying...

It is not state of a port in my case at least. Each time I run cypress script the new port number is being used for connection, besides these ports are not listening to any app either:
e.g.

netstat -ano | find /i "54300"
TCP 127.0.0.1:54305 127.0.0.1:54300 TIME_WAIT 0

Here is the full trace:

Cypress failed to make a connection to the Chrome DevTools Protocol after retrying for 50 seconds.
This usually indicates there was a problem opening the Edge browser.
The CDP port requested was 56212.
