This may be the problem for your game app Malicious or Corrupted. The following troubleshooting checks can solve this problem.
Clearing cached data can free up needed space by removing temporary files. This is a short-term solution. Over time, cached data will build up again.
To clear the cache for the app:
Open your device's Settings app Settings app.
Tap Apps & notifications.
Tap the app. If you don't see it, first tap See all apps or App info.
Tap Storage and then Clear cache.
Check App Update > Log out Game > Restart device > Open Game & Log in.
If the problem remains the same after the troubleshooting checks, I would suggest you uninstall and reinstall the game app because In some cases, such problems occur when the game app is corrupted. You will lose the accumulated boosters to do this, but your game progress and gold bars will be returned.
Please let me know.
