low level fatal error in packaged game

The game works fine in editor without any problem but when I package it, it gives this issue:

LowLevelFatalError [File:D:\build\++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\Serialization\AsyncLoading2.cpp] [Line: 8281] ObjectSerializationError: /Game/Blueprints/PlayerCharacter_BP (0xAE3D211A21E6C2FA) /Game/Blueprints/PlayerCharacter_BP (0xAE3D211A21E6C2FA) - SoundManager /Game/Blueprints/PlayerCharacter_BP.PlayerCharacter_BP_C:PlayerSoundManager_GEN_VARIABLE: Serial size mismatch: Expected read size 94, Actual read size 50

And the thing is that PlayerSoundManager was old name of my component which I’ve changed to SoundManager and for some reason its still linking to that.
I tried deleting saved/intermediate/derivedDataCache and removing the component in my blueprint and readding it. It still gives this same error on launch.

And even after completely removing the component from my BP and then packaging the game still gives this issue even tho the component isn’t present in the BP.

Looks like it is the Async not the class to me. For a sound manager class it would seem that you want this loaded before anything starts - is there a way you can force this to be loaded so it is actually created before it is used? I am not a programmer just a level designer so take this idea with a grain of salt. I got this idea from it running in the editor because that is a much looser environment then a packaged game so it has time to load.

The problem is solved and it was the corrupted BP. I just duplicated the BP, removed the old one and readded the component in copied BP, recompiled and saved and it solved the issue.
