Unreal VR problem - Stuck on a different menu when I launch my project

Hello i create this post because I’ve got problem with my vr scene.

For the context, i create a Vr scene in unreal engine 5.3. I export the scene and after that i test it with my first computer. My first computer have poor performance, but my scene work, and i can naviguate in the project when i start it.
When i test the scene with my second computer, i can see in the the project on my laptop screen , but when i put my headset i see the steam menu vr like you can see in this image :

Please if someone can help me, i don’t unterstand why my scene don’t work…

I download the latest version of my graphic card
I download the last version of Viveport
I reconfigurate my viveport setup for the headset
I reconfigurate my steam Vr application for the headset
I restart my laptop multiple time

I know it’s not a problem with my scene because with my first computer all is ok.
I use the same headset and the same file project for the 2 case.

I hope someone can help me i don’t unterstand.
