Need HELP with my first mod, NoSuchMethodError

[ByRodrick]

Hello, I just finished my first mod for MC for 1.19.2, I've used:
IntelliJ 2024.1.3

Forge MDK 43.4.0

SDK 17.0.11 (Adoptium)

Basically, my mod plays scary music at night time, stopping any music played by the game. For that I needed to access via reflection to a private MusicManager.class attribute (SoundInstance currentMusic), and the management of this is giving me errors (I think).

Here's the full stacktrace:

Here's my code, the most important lines are at the start of the class and the start of onWorldTick(). These lines manage the private attribute (currentMusic) and the exception fires at line 64:

MusicManager musicManager = Minecraft.getInstance().getMusicManager();

Anybody knows what is happening????? I've spent 2 days trying to find a solution and I can't get it 
Really appreciate your time
