Android 9.6.0库中的Firebase proguard错误

在将Firebase更新到最新版本后，我在更新到Firebase 9.6.0后的发布版本中开始出现以下proguard错误

它在Firebase 9.4.0中运行良好，但在9.6.0中，我无法构建它

错误消息：

我的程序规则：

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in C:\Users\parth\AppData\Local\Android\Sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.

# For more details, see

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
