React Native crash release build - FATAL EXCEPTION: create_react

There is no problem in the development environment, but when I get the release build, the app crashes. (Android) I created a new project (v0.68.2), I didn't make any changes, the room crashed in the same way.

npx react-native run-android --variant=release

FATAL EXCEPTION: create_react_context

java.lang.RuntimeException: Unable to load script. Make sure you're either running Metro (run 'npx react-native start') or that your bundle 'index.android.bundle' is packaged correctly for release.

CodePudding user response：

The Android Gradle Plugin version was 7.0.4 when the project was first created. Android Studio version asked me to upgrade to 7.2.1, so I upgraded. It worked when I downgraded the version to 7.0.4.

android>build.gradle

classpath('com.android.tools.build:gradle:7.0.4')
