mixed reality portal keeps restarting when launching any app

Hello! I've recently bought my lenovo explorer, setting it up was easy, the mixed reality portal (cliff house?) runs smoothly without any problem. I can even place new apps on the walls, etc., but when i want to launch any of them the screen in the headset and on my laptop goes black, and the portal is restarting with the windows logo and the "getting things ready" text. After a few seconds I am again in the cliff house, and everything works fine. The problem comes up with all the apps, even the simple windows ones, like the calculator.

I have a dell precision 5510, the specs meet the minimum requirements except the gpu, which is a quadro m1000m, but again, navigating the cliff house is a smooth experience.

Did anyone met with this problem before? I would appreciate any help!



  • I have the same problem, the same laptop (Dell M5510) and the same MR device (Lenovo explorer), i think that the problem came from the GPU as it is lower than the official demand. If you have solved it by other methods, please tell me too, thanks!

  • I also have the same problem on the same combination of a laptop (Dell Precision 5510) and MR device (Lenovo explorer). I noticed a 100% spike in both Intel HD GPU and Nvidia Quadro M1000M card performance just as the restart occurred. Let me know if you find any solutions. I am specifically wondering if one can launch an MR app without going through the Mixed Reality Portal.

  • The same issue occurs for me except for the MR Device consistently restarts without any input needed

  • Same thing. Mixed reality portal keeps popping up. It is causing me major issues.

  • Same thing. Samsung odyssey. I just start the mix reality app. Mine worked until I updated to Windows 1803.

  • I'm having the same issue and I just bought the HP WMR headset a few days ago. I can load Cliff House fine, but anytime I launch an app, it'll crash and I'm sent back to Cliff House.

    Dell Precision 5520 w/ Quadro M1200. I'm also running Windows 10 Build 1803. I'm trying to get it to work before I have to decide to return the headset or not.

  • Did any off you guys have an update? or a fix? i just reainstalled my whole pc , but nothing worked ;(

    Same issue on my Dell Precision as well. I noticed in the event log that the dwm.exe has a failure in the ntdll.dll each time. Here's the event log details:

    Faulting application name: dwm.exe, version: 10.0.16299.15, time stamp: 0x7f22d77c
    Faulting module name: ntdll.dll, version: 10.0.16299.492, time stamp: 0x1ef3a73c

    Fault offset: 0x00000000000a3e1a

    Faulting package full name:
    Faulting package-relative application ID:

    Looking further at the event logs, I also see the following warning:

    The Desktop Window Manager process has exited. (Process exit code: 0xc0000008, Restart count: 1, Primary display device ID: Intel(R) HD Graphics 630)

    Evidently the HDMI port on the precision is using the integrated HD Graphics rather than The Quadro GPU. I'm suspecting that launching the apps is having issues trying to negotiate between the dual video cards on the Dells.

  • We are running into this as well. Did you find any kind of fix for this?

  • I'm getting this stupid issue too. I just recently bought a PCI-E usb expansion to try and fix this, and I'm still getting the problem
