Dimension on Mac don't start correct

Hi there,

I wanted to get a look at Adobe Dimension, but the program don't start correct.

I get the welcome screen and afterwards the window is empty. Sometimes part of text and buttons appear.

I tried every version, and they're all with the same problem.

2.3.1 doesn't go further then the welcome screen.

Does anyone know what this could be and how to solve it.

Thanks, Michael
