Fresh React-Native project show white screen

I started a new react-native project, but the latest init shows me a white screen.

On old react-native project, i don't have this problem.

Kindly guide me how to fix this issue.

You can see my script :

#!/bin/bash
JAVA_HOME=$(grep JAVA_HOME .env | cut -d '=' -f2)
ANDROID_HOME=$(grep ANDROID_HOME .env | cut -d '=' -f2)

rm -rf .cache
export JAVA_HOME
export ANDROID_HOME
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

node ./node_modules/react-native/local-cli/cli.js run-android
node ./node_modules/react-native/local-cli/cli.js start -- --reset-cache

Thank you community !
