Frequent crash when exiting Unreal Play-In-Editor with Oculus Rift connected

I'm experiencing a frequent crash shortly after I exit PIE:


  1.  Fatal error: [File:D:\Build\++UE4\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Util.cpp] [Line: 345] SwapChain->ResizeBuffers(1,SizeX,SizeY,RenderTargetFormat,DXGI_SWAP_CHAIN_FLAG_ALLOW_MODE_SWITCH) failed at D:\Build\++UE4\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Viewport.cpp:235 with error DXGI_ERROR_INVALID_CALL, Size=724x124 Format=DXGI_FORMAT_R10G10B10A2_UNORM(0x00000018)

The crash appears to occur most frequently if I'm exiting a non-VR
PIE session, but have a Rift attached. Does not appear to occur if I
unplug the Rift.


Any thoughts on what's going on here & what to do?


Here's the full callstack:

      Update: I was able to verify that the problem does not appear to occur when using a Vive, so for the time-being, we're out of the woods since I can use the Vive for the client presentation, but if possible, I would like to have the option to put the Rift back into service when needed. I can see from forum activity elsewhere that other users appear to have encountered this issue as well. Is anybody aware of any solutions?

      Thanks!

      Hi @kmack
      I'm using the Oculus version of UE4 4.19.2 with Rift/Touch and I don't have that problem .

      I'm having this issue or very similar too in at least UE 4.18-4.21.

      With the Oculus plugin enabled, exiting PIE almost always crashes UE within a couple of seconds (both in viewport and VRpreview). However, occasionaly it doesn't and stays stable no matter how many times I start and stop PIE.

      If I disable the Oculus plugin, this never happens.

      In the log I find this: LogD3D11RHI: Error: SwapChain->ResizeBuffers(1, SizeX, SizeY, RenderTargetFormat, DXGI_SWAP_CHAIN_FLAG_ALLOW_MODE_SWITCH) failed
       at D:\Build\++UE4\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Viewport.cpp:257
       with error DXGI_ERROR_INVALID_CALL,
       Size=678x96 Format=DXGI_FORMAT_R10G10B10A2_UNORM(0x00000018)

      Disabling dx11 removes that line but doesn't fix the issue.

      Hi @kmack,

      in case you'd still be having this issue (or someone else runs into it), this solved it for me:

      "The devs identified so far as entering in conflict with the game are ASUS Sonic Studio, MSI Afterburner and NAHIMIC. If any of these programs are present in your computer and running during your startup, please disabling it and initiating the game again."

      Uninstalling Nahimic did the trick in my case.

      cheers,
      Yoerik
