quick work around could be to disable the discord service. or to not run discord on your host.

i.e. in settings.yaml

Game:
        Mod: ra
        EnableDiscordService: False

Do you have Discord installed?

[RoosterDragon]

Theorizing: DiscordService.Service has a guard to return null if EnableDiscordService is false. Lots of stuff checks for a null Service to skip logic. But if Game.Renderer == null then Service/instance is created, but client is null.

Then in UpdateParty it could be dying on the null client?
