Looks like the BaseExtension was removed with the latest AGP 9 release:
The extension wasn't removed, but it's not created when the Hilt plugin checks for it. Unsure where the issue lies for this, but leaving this issue open.
Caused by: java.lang.IllegalStateException: Android BaseExtension not found.
