a failure occurred while executing com.android.build.gradle.internal.tasks.workers$actionfacade

I have seen a lot of sources about this problem but nothing really worked, I want to publish my game to play store but when the abb built and When I Upload it to play store It says that the target must be 30 but my highest API level downloaded is 29 so I downloaded API level 30 but I can't build the game now and it says "a failure occurred while executing com.android.build.gradle.internal.tasks.workers$actionfacade" Someone said to edit the gradle file and change the level to 30 but I have no idea how to to this, If anybody have solution please answer..

Thanks...
