so ever time i try to replace my realm with a world that has a certain mod with exspiremtal fetures it says an error has occured

So every time I load up a world with experimental features in an addon(for example I will have vantage magic linked in attachments but a whole lot of other addons don't work) then when you try and replace it with the world so you can play with addons with friends it will give an error message saying "an error has occurred" pls fix the error or make it so you can just add experimental features on a realm with having to replace it
