unity build error occurred: Execution failed for task ':launcher:mergeDexRelease'

Question

I used google-signin-unity plugin on my game. But this issue happened when I built android apk on unity. unity version is 2022.3.16f1.

What went wrong:
Execution failed for task ':launcher:mergeDexRelease'.
A failure occurred while executing com.android.build.gradle.internal.tasks.DexMergingTaskDelegate
There was a failure while executing work items
A failure occurred while executing com.android.build.gradle.internal.tasks.DexMergingWorkAction
com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:
Type com.google.googlesignin.GoogleSignInFragment$State is defined multiple times:
 >D:\project\Library\Bee\Android\Prj\IL2CPP\Gradle\unityLibrary\build.transforms\b912aa27fde5edc070cb71db7c70b335\transformed\classes\classes.dex, 
 >D:\project\Library\Bee\Android\Prj\IL2CPP\Gradle\launcher\build\intermediates\external_libs_dex\release\mergeExtDexRelease\classes.dex
Learn how to resolve the issue at https://developer.android.com/studio/build/dependencies#duplicate_classes.

It seems like files in folder below are defined multiple times in another place? native-googlesignin\src\main\java\com\google\googlesignin

I have searched for fixing long time but it still no solution. (gradle and AndroidManifest file setting etc) Does anyone have any idea?

Go to Project settings-> Player -> Publishing Option -> Minify and select "debug" if u are still producing the game and finally when you need the official release set it to "release"

Modify the following lines in your settingsTemplate.gradle file. These changes ensure proper functionality when using the Google Sign-In plugin
