After clicking "OK" on the "Export Mixdown" screen, the "Please wait..." window will appear, but if you press any key such as the space key before pressing Cancel, you will not be able to press the Cancel button.
If this phenomenon is only me, I should always be careful not to accidentally press any key, but if everyone else is in the same situation, please improve the StudioOne program.
thank you!
Here are the settings for reference.
