Direwolf back has a Texture file in it that violates resource pack rules. If you scan through texture folders that will cause the crash.
That is not a bug in ic2c look into the direwolf pack and search for a texture that has a upper case texture.
(its most likely a custom resource pack or something.

thank you for the fast response.

Where may I find the texture? in the resource packs folder?

@Maxster991 honestly i have no idea. I never installed the pack or got explained by others where the issue file lays.
Just search for that file name.
