"Link to crash log: (please use a paste site such as gist, do not attach the .txt or paste the log inline)". We need one, otherwise we can't tell what's happening

I thought that is what https://gist.github.com/JACKO4590/b7e3a94da3be0cb84f035bbd37bcfc56 is. Is this what you need?

Ah, did not see that.

It appears that is issue has been reported here before, but is caused by Optifine. I don't use it myself, but the fix is either to update or change version.

omg yes looks like removing that makes it work. Ill post on the hexxit discord as well and at lease now I can play. Thank you
