[Bug] Transformed Fusion Primaries Crash When their Cry is Played; Summary Screen, Sound Move, Evo., Move Learn

[Snailman11]

Describe the bug

After Splicing a Pokémon that has been Transformed as the Primary of a Fusion, checking that Pokémon's Summary screen, allowing it to learn a new move, evolving or changing its form, or using a Sound-based move will crash the game.

-The Cry played for a transformed Pokémon will always be the Cry of the Pokémon it has transformed into, rather than the Cry of the actual Pokémon.
-The crash does not occur if a Pokémon Faints, and it cannot be sent out without Transform being reset
-New moves from the Splice can be learned, but they replace the moves that were previously in those slots after Transform ends.
-Occurs even if the Secondary and Transformed material matches the Primary Species.

Reproduction

Use Transform or the Imposter Ability to transform into another Pokémon using Imposter, then use DNA Splicers with that Pokémon as Primary and any other Pokémon as Secondary. Then use a Sound-Based move like Growl or accept the learn move prompt from Splicing.
