Creator 3.8.3 simulator display size

ChatGPT

In creator 3.8.3, after creating a HelloWorld project,
no matter how I adjust the Design Width and Design Height in Project Settings,
the Simulator always displays in landscape mode.

How can I correctly adjust the size of the simulator? Thank you.

First, open debugger of simulator.

Then change resolution or direction over here.

Thank you very much for your answer. This question has been bothering me for several days. Thanks!
