Oucular does not work in the package

hi

I developed the program in Ouclus and made the package after the work was completed.

I checked the “Start in VR” checkbox in the project settings,

VR Preview was not a problem in the editor.

But when I run the built file, the game plays properly on the desktop screen,

In Oculus, the screen is black and only the sound is played properly.

If I shake the Ouclus from side to side, it seems that the screen of the desktop is shaking properly.

Can you help me?
