IOS Simulator shows very small iPhone screen

Hello!
I have a small problem starting with xojo 3 hours ago:
Building a IOS Projekt (QuickStart IOS Projekt) works fine until I press the “RUN” button.

It changes to the “Simulator” but the picture of the iPhone 8 has only the size of 2 cm x 5 cm !!
I see no button only the litte rectangle is whit.

If I restart simulator>Device>Restart I got the home-screen in normal size.

Thank you very much if anyone could write me hint how to solve this problem!

Greetings and “Happy Eastern” to everyone

Wolfgang

Thank you!
I solved the problem by myself.
I had to resize the small rectangle and make it bigger > now its ok
