pokemon white 2 crashes when i see my pokemons or when i interact with specific npcs

[Elericowo]

when i randomize the game it causes it to crash when i see the stats of my pokemon or when i interact with specific npc, also i dont know if the size of the rom should be halved from 524mb to 281mb when it randomizes, i've seen people with similar problems saying it's the fix music option but that option doesn't appear when i load the rom, also the rom of pokemon black that i use i downloaded it from the megathread, https://r-roms.github.io/megathread/nintendo/#nintendo-ds ,

System (please fill in the following information):

• Operating System: win 11
• Randomizer Version: 4.6.0
