It was fine one day and then without me touching it in anyway it crashes every time I click play on the mincecraft it loads, and then crashes giving me this https://pastebin.com/wC0GxBxq for the crash report. If it requires me to go into the files and meddle with it I humbly request to be pointed towards a guide or instructions as I am not the most tech literate individual. Thank you for any help!
