This is happening when there are no unused resources at all and we have duplicated resources between the feature and base (or different features)

Reproduction here: https://r8-review.git.corp.google.com/c/r8/+/102418

Fix here: https://r8-review.git.corp.google.com/c/r8/+/102626

For the reporter to work around this:

Disable resource shrinking in this case, it will have no effect since there are no unused resources for this build
Use legacy AGP embedded shrinker - set android.r8.integratedResourceShrinking false in your settings
Manually update to a new R8 version (I will post a follow up when this is on our release branch)
