Your driver is causing a crash with new steamvr client

[CelticSpike]

so the new steamvr client that dropped today kept crashing with a critical error as soon as i did anything. I traced the problem to the natural locomotion driver. Here is what my event log says

Once i uninstalled the software and removed the folder from steamapps/common all was fine.
Hopefully someone from Devs see this as i have seen other users reporting the same crash in the steamvr forum

Specifically, the crash seems to be caused when something attempts to access the headset cameras. I was having the same issue, realized it had to be something to do with the cameras, and disabled the camera in SteamVR settings. Stopped crashing. Turned it back on. Started crashing. Checked Event Viewer, saw the same thing you did, uninstalled Natural Locomotion, crashes stopped.

I've been having the same error, specifically when I tried accessing the new SteamVR dashboard when it was introduced in beta. Found out it was NaLo's driver causing the crash just before the public release of 1.10.

Confirmed. I too, am receiving the same error -

Had the same problem here

[OscarParrao]

Same problem with me. It's a pity because I was playing TWD:S&S and it was wonderful till the release of Steam Vr Beta. Hope a solution will come soon!!!

A brand spanking new NALO user, just purchased the app this evening, and ran into this problem when trying to configure NALO for Skyrim. As soon as I clicked on the system button the new steamVR curved dashboard started acting funky, and then crashed.

Since my priority was to get NALO running with Skyrim, in order to test it out, the fix used was to just disable the system button as part of the NALO profile. After seeing some of the posts in this thread, guess I'm going to test out disabling the camera and see if that is another work around.

Also, ever since installing NALO it never allows steamVR to fully close out cleanly ,e.g. if I exit steamVR then open it up again, steamVR will throw a 1336 error, " an error occurred while updating SteamVR (app running)". Only way to clear it is to exit then restart the steam app.

NaLo is basically one of those things that you love when it works and uninstall at the slightest hint of unexplainable problems with SteamVR. I've had to nuke it several times in the past, it just doesn't play nice. It eventually gets fixed but like... don't get too much in love with using it.

[marvinthedog]

I solved this by simply disabling the camera in settings. Of course I had to uninstall NaLo first in order to access the camera settings but after that I could install it again and it worked without problem.

[spacegeek.2048]

Thank you, disabling the camera is indeed a temp fix. No need to uninstall though, just disable Safe mode when prompted and disable Camera from the SteamVR settings from the desktop. I hope this is fixed soon, but at least I can play now...

[Androktasie]

Same issue here, and same workaround. Disabling the camera worked for me.

Yes, we can reproduce it and we are trying to fix it.

[pix]

We just published the fix!

[spacegeek.2048]

Awesome, thanks!

[mm_half3]

so how do we get the published fix? I figured if its not a new stable release it would be in the beta releases. Read the post on how to use the beta in the beta pinned thread, but when I right click on NALO/properties/betas, there is no option to opt into the beta. Only options are:

None-opt out of beta
previous_version.

and Enter Code for private beta.

Is there some guidance on how to get the published fixes for this app?

Thanks,

[Androktasie]

Can confirm the fix worked, thanks for the update!

@mm_half3, it's published as a stable release, not an opt-in beta. Just launch NaLo from Steam and it should take care of the rest.
