I understand that you're experiencing a genuine issue. The game’s security system might be detecting modification apps, which could be related to your device itself. I recommend trying another device or using a VPN. Sometimes, the problem can vary from device to device. Unfortunately, there's no one-size-fits-all solution here; it requires some troubleshooting.
For us, the issue boils down to two possibilities: either the game’s system is banned you, or there are indeed modification apps present. Please test on different devices to find a stable solution.
