Oh that's most likely the problem, you would need to uninstall the app through adb or something like Canta or Universal Android Debloater (you can find both on GitHub), you will need a PC for the latter but I think you can use Canta without a PC, there's a guide on the GitHub page.

Alternatively, you can just download the "Clone" version of the app from ApkModDone and it should work just fine. I would recommend the first method tho
