SteamVR critical error, WMR error code 14-1

[Laywolf]

I can't play all VR applications bound with SteamVR includes SteamVRHome. This occurs after my Windows update to 1903(OS build 18362.267).

All common trouble shooting(reinstall WMR, SteamVR, graphic driver, downgrade graphic driver, testing beta branch) are done, but they didn't bring me any solutions.

When running SteamVR, all displays (desktop display, HMD display) stop for a while. After that, some applications (chrome, discord) were blacked out, and they did not come back to work. Finally, sometimes Mixed reality displays an error code 14-1.

This error just occurred on SteamVR, so I left this request for help here.
Please help me for my VR life.

Is error code 14-1 a USB error code?

My headset did this last weekend out of the blue, never had an issue like it, it turns out that USB 3 has some extra power pins or something, and for some reason, my PC shutdown those pins so the headset was only detected as USB 2 and gave me an error code something like 14-1, figured out I had to shut the pc completely down, unplug the headset, and leave it unplugged, then power up thew PC, once fully booted, plug the headset back in and bingo, works perfect again.

I know USB has some thermal and power overload protection so I will assume something tripped that, and the only way to reset it, is to power off and remove all USB devices, power up and everything is all good

Try to disable fast startup.

Thank you for your replies.
I tried all suggested solutions, but they can't help my situation.

Any other suggestions for this problem?

+ SteamVR displays an error prompt with these messages (same as before, and now also):
Unexpected SteamVR Error
SteamVR has encountered a critical error.

mine went to crap again, had to plug in a powered usb3 hub, now my headset works perfect again.

Laywolf, I have the same exact problem as you - error 14-1 and Steam critical error. It seems the video driver is crashing as per the logs....Display driver nvlddmkm stopped responding and has successfully recovered.

Here is the explanation of the 14-1 error...

Likely reason for the error code: Mixed Reality Portal is having trouble initializing the graphics and composition stack.
Desktop Window Manager (DWM, a key component of the Windows Graphics stack) may be crashing. Check the Application Event Log (using Event Viewer) to see if this is occurring.
Try a clean uninstall of your graphics driver, and then install the latest graphics driver from the graphics card manufacturer's website.

I just had the same issue after updating Windows 10 to 1909. I thought that it was related but finally found the solution : I had disabled the Memory swap file to save some space on my Windows partition. After re-enabling the swap file, SteamVR works again ! It swaps 60 Mo at startup, no matter the current memory usage

How do I re-enable the memory swap file?

Here’s an article on how to disable the swap file : https://wpguru.co.uk/2024/02/how-to-disable-the-windows-page-file/

Just check the "system managed size" at the end
