If you are seeing the SteamVR Error Code 436, then see the fixes given below to fix the issue.
- Update Graphics Driver

- Reinstalling SteamVR
- Disable the integrated Graphics card
Let’s get started.
1] Update Graphics Driver
The problem can be resolved by updating the Graphics Driver. So, you should start by checking the status of your Graphics Driver. If it was recently updated then it ain’t the reason. However, if you haven’t updated in a long time then upgrade your Graphics Driver. You can try checking for your Windows Updates as updating the OS can update all the drivers. Also, you can use driver update software to keep your driver updated.
Once, you do that, launch the program and check for any errors. If you are still seeing the error then move to the next fix.
2] Look for loose connection
As mentioned earlier, tether cable is the main part of your setup, and if it’s not tightly connected to the setup, you will see the error code in question. You can make sure that the tether cable connecting the headset to your PC is connected correctly.
After making sure that it’s firmly plugged in from both ends, restart your PC. Now launch SteamVR, see if the error is resolved. If the error persists, try the next fix.
3] Unblock SteamVR add-ons
If there was a sudden crash then it’s more probable that important add-ons are blocked. So we are going to unblock all the add-ons and check whether it’s of use or not. Let’s see how to do the same.
- Disconnect all the VR equipment including the VR headset and Link Box.
- Click SteamVR drop-down menu and navigate to Settings.
- Click on Startup/Shutdown.
- In the Startup option, click on Manage SteamVR Add-ons.
- Select the UBLOCK ALL option.
Usually, this will unblock all the add-ons. If any add-on is still blocked, you can manually unblock it. Then, close the app and connect the VR headset again. Relaunch SteamVR if you are still seeing the error.
4] Reinstall SteamVR
If the above fixes didn’t resolve the issue then uninstall SteamVR. Uninstalling can get rid of any corruption in the installation files. Reinstalling SteamVR simply put an end to the issue. Go ahead and uninstall the SteamVR program from your computer, then download it back on the system. Finally, check if the issue persists.
