问题
I have just updated the Android Studio from 3.5.3 to 3.6. After this update, I have updated the Gradle and Android SDK Build Tools as well. Now the Gradle sync is failing with these errors:
1. org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfiguration$ArtifactResolveException:
Could not resolve all artifacts for configuration ':classpath'.
2. org.gradle.internal.resolve.ModuleVersionResolveException: Could not
resolve com.android.tools.build:gradle:3.6.0.
3. org.gradle.internal.resolve.ModuleVersionResolveException: No cached
version of com.android.tools.build:gradle:3.6.0 available for
offline mode.
Looking at the 3rd error it seems that Offline Work option needs to be disabled in Android Studio Settings -> Build, Execution, Deployment -> Gradle. But the Offline Work check box is no where to be found in the said settings. Is it the actual problem? If yes, then how it could be disabled in Android Studio 3.6? If no, then what is the problem here?
I have already tried Invalidate Caches / Restart but it did not help.

Run to the very same error a while ago. This worked for me.
From the Android Studio 3.6 new features blog post: New location to toggle Gradle's offline mode To enable or disable Gradle's offline mode, first select View > Tool Windows > Gradle from the menu bar. Then, near the top of the Gradle window, click Toggle Offline Mode Gradle offline button in the Gradle panel
Source: Cannot enable Gradle's offline mode on Android Studio 3.6

Ran into the same issue and deleting ".idea" folder inside project directory and deleting ".gradle" directory from home helped me resolve the issue.
