You coult try to rebuild your database:

If your situation doesn´t improve after that, please reinstall the game.

Good luck 🙂

i did the rebuild database it didnt work, how th ereinstall will help me?

I don´t know if it will 100% help you, but it seems to be the only thing left to do.

Something is wrong with your game data (or even your HDD), so we´ll have to try something.
