Map doesn't not appears in HTC Vive

Hello Unreal Community,
When i launch my packaged game, i can’t watch one map in HTC Vive. It appears on desktop but not in the gear. Moreover the map works good in editor. All of the others maps works good.
What i can do?
Thanks a lot for answers.

PS: Can you correct the mistake in the title please?

I created a new project and i reimported all the content. It’s works. You can check the post. Thank you.
