The reason why you cant have this mod while having gacha club is because i think this mod took gacha club and just remade and added stuff, and the device will think u want to have 2 gacha clubs (thats what i believe at least)
It's because the name of the packages are the same, so your device will think that gacha luminal and gacha club are the same app, you can solve this issue by changing the name of the package with an apk editor, this method worked for me and I think it will work for others too
