After investing lots of time, I didn't find the exact issue. I am showing the list of data using Flatlist component and each item of the list, contains an icon on clicking which opens a modal that contains a dropdown picker and a TextInput component and when I tap in textfield it opens an keyboard and then suddenly closed it and the modal also.

My React-Native Packages Detail: react: 17.0.2, react-native: 0.66.0, react-native-screens: 3.13.1, react-native-gesture-handler: 2.4.2
