I’m having difficulty reproducing the crash on my machine. I have the Ouculs connected via Direct mode and can launch the editor and open a project without any crash. Are you launching the binary version of the editor from the Launcher or are you using a source version? Does the crash happen when launching the editor (trying to get to the project selection screen) or when opening a project? Having the log files from the crash will also help shed light on the cause. This wiki page gives the default file path for where the log files are saved: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums
For the time being I would double check the runtime (0.4.4) and the Firmware (2.12) and possible try updating them both to be sure.
