How do I restore the Bluetooth app of Yamaha psrsx 900

First you may want to reset the bluetooth data on your mobile device and try matching it again.

The stock answer to all things Yamaha is to save all user data to memory stick then reset the keyboard.

You may also like to check if you have the latest OS installed, if not install it.
