IOS App crashing on startup

I am trying to test my app on a real device and I have uploaded it to itunesconnect and installed it on my phone using TestfFlight but the app crashing immediately after the splash screen.
And I check the Crashes and found this “-[CDVViewController configFilePath] + 332”.
this is my first-time uploading app so I do not know what I am doing wrong

You have to show more of the crash log.

Did you test the app before on your local device?
