Still having the same problem in 1.5.0 - I’m getting: The following classes could not be instantiated: - com.google.android.material.bottomnavigation.BottomNavigationView

Exception Details: java.lang.IllegalArgumentException: Motion easing theme attribute must be a string at com.google.android.material.motion.MotionUtils.resolveThemeInterpolator

Only going back to 1.4.0 seems to work.
