A friend of mine created a modpack with this mod in it. I checked every mod and it happens that this one doesn't allow curseforge to launch the game. Basically it opens the dashboard for the game but the game itself never opens and it stays blocked.

If you have an idea of why this happens could you please tell me. Otherwise i'll try to fix it myself.

Thank you very much, have a nice day.

Have you installed CreativeCore? What minecraft version are you using? NeoForge or Fabric? There should also be a crash-report which tells a lot more. You could send it to me.

I think this issue is fixed in the newest version.
