I have uninstalled both both minecraft and cured forge, and I keep crashing as soon as I enter the server. The error is on my side since the owner of the server and other players can log in without an issue.

attached is the log of the crash

Any help is appreciated!

Please update to the latest alpha, you're several months out of date (based on when the issue was created) and it's likely this has been fixed by now
