Seen these before and tried using various versions of forge and tried downloading at least 30 versions of Moonlight starting from the most recent with the most recent version of forge and the result has always been the same.

If I install an old enough version it will load but not with any mods. Not sure what to do besides figure out exactly which version is compatible with which version of Forge.

Figured it out thanks to the discord. Power outage had caused the config file to corrupt.
