Well I have no experience with Mocha CFW, but I don't even see the 2018 version on the Loadiine Compatibility list: https://wiki.gbatemp.net/wiki/Loadiine_compatibility_list
Are you trying to run the game using Mii Maker or SSBB mode? Since it might be a compatibility issue, easiest first step would be to try the other one and see if that works
