To avoid crashing, please recook your scene. We will fix this to not cause any crash in the future, only an error message.
Please also make sure that you change your Aximmetry Camera to the latest version in your Unreal scene. Forgetting will not cause any crash, but your scene will not work properly.
What parameters are needed to properly cook unreal for Aximmetry? I am trying to cook the Studio C from Unreal for Aximm. It keeps failing.
