Android simulator cannot display apps correctly (Android studio)

I'm making a basic phrase application (I mentioned this in the previous question), and then everything changes. However, the emulator can't display the application correctly at all. This is a preview in the studio:

This is what the simulator displays:

There are no errors in my code, and all Android studio components are up-to-date. What's going on? This is my XML:

</GridLayout>

resolvent:

When the layout gravity is set to fill, it fills its container. That's why it only displays the first button

Perhaps the current simulator encountered some problems in rendering GridLayout, so the root layout became a container for buttons

I tried your XML file and it works perfectly on both simulated and real devices
