Unreal builds are crashing at startup on Focus Plus

I am using Unreal Engine 4.22 and WaveVR version 3.1.94. When I build my project and run it on Focus Plus, it crashes immediately. The error shown in the log file is below:

Has anyone experienced this error? Any help would be appreciated.

I was able to figure out the issue. Since I was using Oculus 4.22 branch of UE4, it was using IsOculusMobileApplication() function to determine if it is going to render in VR or not. Since the binary UE4 4.22 uses IsGearVRApplication() to determine the same, it was causing issues. To fix this, all I had to do was replace IsGearVRApplication with IsOculusMobileApplication in WaveVR_UPL.xml file located in <ProjectDir>/Plugins/WaveVR/Source/WaveVR.
