Hello InsomniaLibro!
Well, it should be compatible with Apple Silicon Macs according to the build settings being set, but to be honest I haven't test it using one, I've only tested the app on an older Models since I don't have access to macs using Apple Silicon.
When you start the app, it should show the Demo character with a little animation on its antenna and the Quick Setup must be run at least once in order to do more stuff. To Show or Hide the Options Menu you can use the keyboard shortcut: Ctrl + M or you can Also click on the Top Edge of the Window as an alternative.
Is any of the above showing or working?
When you mean that it's frozen, is it only the app window itself or does it affect the system overall?
