Hi @brianoh Thank you for your attention. If the open button is disable, that means the window engine have not created. In most case reason cause this problem is that the permission don't grated, and the service start failed. Please see if issue #3 can help you. Also you can try to download this repo and run the example app to see if it works.

BTW the ? null warning don't matter.

I hope the information can help you. Thank you.
