The report provides no source files, tests, or entry points; begin by reproducing the crash with the listed Android, Java, Gradle, and Booster versions and inspect the stack trace around the missing MessageProvider class. Done means identifying why the packaged app cannot load that class and verifying that the application launches successfully after the build.
