Whenever I've tried to load a client version of my test mod as I'm trying to make one based off a friend's w his permission, i keep stumbling upon this crash:

If anyone can help me, please do. If I must, I will use applications such as TeamViewer so that those can come and see what I may or may not have done

nvm, fixed it

Hello, what did you do to solve the problem?

About all forums just reply with "this is an old version we dont support it" etc.

French forge forums don't know the answer, and the only thing i found (deleting users/USER/.gradle) did not work.
