EDIT If anyone needs a quick fix without downgrading AS it compiles without errors on alpha using Android Studio Bumblebee Canary 2 and AGP 7.1.0-alpha02.

The Android Gradle Plugin team is aware of the issue and a fix for this will be available in AGP 7 beta05.

Sorry all for the issue, AGP is expected to have a release sometime next week for 7.0-beta, if all goes well. Meanwhile using 7.1-alpha02 should work.

And just for context, this is related to Hilt’s bytecode transform which uses AGP’s new ASM pipeline starting in 4.2 which is way more efficient and correct than the ‘previous’ version. The APIs for the ASM transform are planned to become stable soon in 7.0 so hopefully, in the near future this should be less of an issue.
