After downgrading from Gradle 6.1.1 to 7.2 and Android Gradle Build tools 7.1.0 to 4.0.1 (by switching branches in Git) I got the following exception in the Run console (tool window) of Android Studio Bumblebee 2021.1.1 (when trying to run the app on a device):
Unable to determine application id: com.android.tools.idea.run.ApkProvisionException: Couldn't get post build model. Module: My_App.app Variant: debug
The Grade build runs successfully but the app won't be installed in the device.
