It has a guide and a Switch.bat for making this process easier. Make sure you navigate to %localappdata%\Eden (can type that into a Windows Explorer file path and hit enter to bring you to it), don't just manually type it in for your antivirus as you need the full file path, not the file path with %localappdata% in it.
Fix: Disable autologin and try to login manually.
This page should hopefully be able to help you fix your problems, however, if it does not, please feel free to ask in the 'Tech-Support' channel on the server discord. It's a constant work in progress as issues are resolved or if new ones arise. This is the troubleshooting guide for Eden.
