First, I thank everyone who has helped! I started to do some troubleshooting and I found out that the ConnectedTexturesMod was messing up literally everything, so I installed it and things are now working! I give all of you a HUGE thank you!
I am making a pretty big mod pack on the Twurch launcher (Twitch + Curse) and I tried to open it up. It started to crash right at 3/7 where it loaded textures and sounds. Here is the logs of the mod pack turning on and then crashing. If anyone of you could help me then it would be greatly appreciated!
