It is failing on the ProfileSanitizer function of the mod RaiRaiTheRaichu-AllTheClothes. I presume it may require a profile to be set up to work? I don't know you will need to check the documentation.
By the look of it remove that mod, make your profile and away you go?
Of note this board is for support with base game issues, not for heavily modded games, as it will largely be due to one of those mods, especially when the top of your server is filled with mod x "is not compatible with the current version of AKI. You may encounter issues - no support will be provided!"
That was the solution thanks a lot. Sorry if I may have posted in the incorrect place or something. I just didn't really know what to think of what I was looking at and assumed it would be best to ask for help here.
