Thank you for reaching out. I have not seen anyone else report this problem before, so I am not completely sure what is causing it. You can try a few steps that often fix install issues. Check your app list and remove any copy of the game that might still appear, clear your package installer cache, download a fresh apk from the source, and try installing again. If it still does not work you can send me your Patreon username and I can issue a refund if the problem continues.
