Can't get Create: Arcane Engineering to work outside of Curse/FTB launchers

I'm trying to get the C:AE modpack to work in a launcher that isn't curse or FTB. I've tried Multimc, Prism, and PolyMC. Downloading from curse/ftb to those is not working, and also exporting or taking the instance files from curse/ftb and moving them into one of the other launchers isn't working either. Consistently regardless of launcher the game will load and then crashes upon loading a world. The games are loading and playing perfectly fine in curse/ftb, I just would like to not use those launchers if I don't have to

Does anyone else have this problem or any solutions?
