Unity build with admob giving "r8 debrecated" errors

I always get the same error when I use admob or a similar service. There are a lot of topics about this error in the forums, but the solutions I tried did not work. Here are the solutions I tried: Creating custom gradle.properties and deleting the r8 code did not work. Create a custom base gradle template and change 'com.android.tools.build:gradle:3.6.0' to 'com.android.tools.build:gradle:3.4.0' did not work. change target api "Target API Level" to "Android 11.0 (API level 30)" did not work please can somebody help me?> Starting a Gradle Daemon, 1> incompatible and 8 stopped Daemons> could not be reused, use --status for> details>> Configure project :launcher WARNING:> The option 'android.enableR8' is> deprecated and should not be used> anymore.
