App crash after app upgrade due to data store migration in Android

After the app upgrade from play store, getting crashes for the data store. Recently I migrated from shared preferences to the data store. This happening only in pixel 5, and not in android 9.

Below is the log for this crash.

Fatal Exception: d1.n.a: Unable to parse preferences proto.

It is likely that your proto buffer file is corrupt.

One way of addressing this is to add a corruption handler to the creation of your data store.

val context:Context = ... // your context 
val corruptionHandler = ReplaceFileCorruptionHandler<Preferences> {
    mutablePreferencesOf(
       // recover preferences here
    ) 
}
val dataStore = context.createDataStore("data_store", corruptionHandler)
