Hey. It's probably due to an incompatible extension.
If you feel capable, open the finder and go there : /Users/yourname/Library/Application Support/Orion/8E9A26B3-55BD-4683-BD63-8649B6132636/Extensions
The big number may be different, but there is only one. By deleting the folders inside and restarting Orion, it should go better.
