React Native - stuck on launch screen ios simulator

I tested my app on iOS simulator, the build was fine but while running the app, it gets stuck in the LaunchScreen and the following errors are shown in the console.

the android version of the app works fine.My xcode version is 11.3.1.In the Edit Scheme of xcode, I have set the environment variable OS_ACTIVITY_MODE=disable after going through some of the stackoverflow queries.

Can anyone help to sort this issue?
