Bug description and reproduction steps

I have tried to launch Minecraft Forge 1.8.9 with this mod for that version along with the mod called uteamcore (Apparently its needed) minecraft crashes when I launch it with these mods. Is there any reason for this that I should be aware of or does the mod just not work because it's an older version?

Here's the error message if this helps:

Log files and Screenshots

Used minecraft version

1.8.x

Used forge version

1.8.9-forge1.8.9-11.15.1.2318-1.8.9

Used mod version

2.1.1.136

Known to be an issue with other mods for 1.8.9. Do you have the mod patcher installed?

Yes, I do.

Yes, thats the problem. Unfortunately no fix was found in a reasonable amount of time

Oh, should I uninstall patcher?

That's probably the only solution if you want to use music player for 1.8.9

Should be fixed in this version https://www.curseforge.com/minecraft/mc-mods/music-player/files/3841508
