I will show you a perfect way to make GG work! This guide is for those who open the GG and then it closes immediately after the root allow request. So you need root explorer or any other apk that can set permissions to files!
You will go in to GG path folder /data/data/pl.aqua.gameguardian/ and set full permissions to all folders(main path too) and files one by one! Then open GG allow it! Doesn't close anymore!!!!!
