so, I found out that the CustomOST mod i used for my custom track stopped working due to updates, Due to this, I Re-made my Mod to fit with the built-in BeardLib custom Soundtrack asset.
Im new to modding, so the Track will appear in game as ERROR: menu_jukebox_ITF
If anyone knows how to fix this issue please comment,
Other than that, The Track itself works perfectly fine.
