This is apparently an Android Studio 4.1 issue. There's an open ticket for that already: https://issuetracker.google.com/issues/170328018

What really solved the issue for me was reinstalling the Android 11 (API 30) SDK, according to the bug ticket above:

"...there was an issue with API 30 mock jar that was built incorrectly. Can you open Android Studio SDK Manager and try uninstalling the R SDK or any Android SDK Platform 30 please? The Gradle build will auto install it when you try to rebuild after you delete the R SDK."
