Research direction
Investigate the duplicate 'androidx.versionedparcelable.VersionedParcelable' class. Common cause is conflicting dependencies. Check the project's build.gradle for version mismatches or transitive dependencies. Consider adding a dependency resolution strategy or excluding the class via R8 rules. Refer to issue #108 and any related PRs.
