I apologize for taking almost a month to respond, it's been very hectic for me, I know that doesn't help you with the bug in any way but it's all I can really say.
I can't replicate that error even though I've tried to. It looks like the game is trying to load the defines twice but I haven't had that happen and nobody else has reported any errors like that.
Unfortunately I don't know how to fix your issue because I can't get it to happen on my end and nobody in the discord has reported anything similar.
