Sorry to hear you're running into this issue. First, could you please provide me with your
latest.log file? You can find it in the
.minecraft/logs folder. It might contain some errors or other information that would be helpful in diagnosing the issue.
Also, please check in your
.minecraft/wurst folder if the
enabled-hacks.json file exists. This file is responsible for storing your enabled hacks, so if it's missing or corrupted, it could be causing the problem.
Thanks for reaching out, and I'll do my best to help you out!
