Hi! I really need help with my Meizu Pro 7-H.

The device has factory firmware. And in some apps whenever I opened it - the app would randomly shut down. So I decided to upgrage the firmware.

I installed from here.

First the stable version.
After the upgrade, whenever I clicked on the Settings icon - it would show for less than a second the Setting screen - and then the window would disappear, throwing me back to the home screen.

So I tried the beta version.
After the upgrade, whenever I clicked on the Settings icon - it would show for 3-4 seconds the Setting screen - and then the window would disappear, throwing me back to the home screen.

I experience the same 'going back to home screen' issue in many apps.

What can be the reason for this and how can it be fixed?

Thank you!
