GApp endless looping

After FydeOS installation, I tried GApp configuration. Once completed, after the reboot, the Play Store appeared. But clicking the icon, the endless looping keeps on going. I tried to delete GAPP from the store, reinstalled, rebooted so many times. I even powerwashed or resetted FydeOS and started all over again. But still I have the same problem.

Sometimes, I deleted the GApp druing the configuration, but then, the Play Store still existed and it allowed me to install other apps. This was in the state of after I deleted GApp. My goal is to root the device. Any advise on that?

What device?
