Ok earlier I was using the wrong crash log oops. anyway, here it is: https://pastebin.com/zPZs4LvG. The problem: Minecraft stops responding after reading world data. why? idk.

 

Ok so, If you are ever having problems ALWAYS check your crash reports. You can do this by checking installations and then the installation folder. Get your latest crash information, and usually it will tell you if one certain mod is the problem. My case, It was the Pyromancer mod. You can check my paste bin to see just how simple it is. I hope this helps if anyone else finds this thread!
