I've been using minecraft forge for 1.12 fine for a good while, but after I installed the 1.13 forge it hasn't worked. It will keep crashing.

Vanilla minecraft for the latest version works fine.

I deleted the .minecraft file and then forge worked fine.

I replaced the mods, shaders, saves and resource packs folders and then it started crashing again.

It says something about craftstudio, which was a mod I had in my mods folder and then took out but it still mentions craftstudio and still crashes so I'm not really sure what to do.

Any help is great!

Start by removing all mods and then trying to start Forge again. If that works you know it's probably a mod going rogue.
