Is there any known issue or fix to this problem?

I have an Unreal Engine 4.20.2 project on GearVR crashes on any input of GearVR touchpad or controller.
The crash happens on Samsung Galaxy S8 and S7, Oculus GO works fine.

App works in developer mode if I uninstall Oculus GearVR app, start GearVR developer mode (Gear VR Service app)
Since the GearVR service is still running, I can still launch the App, which then works fine and input does not crash app anymore (even touch input on display causes crashes if app in developer mode).

Same problem here. Best bet is still Oculus finding the fix via that forum post
