Unable to Run Appium on device as it gives port busy or connection refused

Hi All,

I have MacBook Pro and have update to Big Sur.
And Appium with Version 1.15.1.
When i have completed the set up in the Xcode, the WebDriveragent is not installed.
When i try to run the test case on my real device(iPhone 7), it throws “Unable to launch WebDriveragent because of Xcode build failure” error constantly. When I have changed the port, it says port is busy or connection refused.
Any help appreciated. Attaching the logs and screenshot for reference.

"app": "/Users/shruthisowmyavr/Desktop/Dialpad.app",

APP for simulator. For real device you should use build ending with “IPA”
