您好，我正在尝试构建我们的应用程序的版本变体，但它触发了以下错误时，第一次运行的应用程序。
复制步骤：
1.构建签名的APK
1.在模拟器上安装apk
1.应用程序崩溃

巧合的是，这只在发布时运行，但在调试时运行良好。我在我的proguard规则中添加了-dontshrink，-dontoptimize，-dontobfuscate，这就是为什么我可以生成堆栈跟踪。
构建等级值

android {
    compileSdkVersion 33
    buildToolsVersion "33.0.0"
    defaultConfig {
        minSdkVersion 23
        targetSdkVersion 33
        versionCode 1
        versionName '0.1.0'
        consumerProguardFiles "consumer-rules.pro"
}

minifyEnabled、textCoverageEnabled、收缩资源全部变为false
Firebase库
