UE5 VR// imported work is working well but new VR starter project has the problem

Hello, I wanna test UE5 VR. I imported the work I was working on, it works great. But when I open the Virtual Reality basic template. the HMD tracking seems work as seen on mirror screen on monitor but it doesn’t appear on HMD, it’s just blank Steam VR page. I’m using Pimax 8kX, Please help me to fix it. As imported project works well on UE5. The default basic template should work as well. I set all rendering setting as imported project but it doesn’t help with it.

Which XR plugins are active in the imported and template project respectively?

Thanks. I fixed it by disable the XR plugin.
