I crashed/can't launch VRChat/other issues

VRChat crashing? Not launching? There's a few things we can try right off the bat to see if you've got something easily solvable. Please follow all of the steps below. If your problem persists, we'll ask you to gather logs and contact our support at the end of the article.

In-App Method (Preferred)

If you can access the application, open your Settings Menu, open the "Advanced Settings" button in the top right, and click both buttons. Restart VRChat. Skip to Final Steps!

If you cannot access the application's Settings menu, move on to Automatic Method.

Automatic Method

Press your Windows key and type "cmd" into your Windows Search bar. Right click "Command Prompt" and click "Run as Administrator". A black command prompt window should pop up. Copy this command with Ctrl-C, and paste it into the window by right-clicking in the window.

rmdir /S /Q %AppData%\..\LocalLow\VRChat\vrchat\Cookies && rmdir /S /Q %AppData%\..\LocalLow\VRChat\vrchat\HTTPCache && rmdir /S /Q %AppData%\..\LocalLow\VRChat\vrchat\Unity && rmdir /S /Q %AppData%\..\LocalLow\VRChat\vrchat\VRCHTTPCache && rmdir /S /Q %TEMP%\VRChat && REG DELETE HKCU\Software\VRChat\vrchat /va

Press Enter. A bunch of files will show as being deleted. It will then ask you if you want to delete all keys under the VRChat key. Press Y for Yes, and press enter. Close the window and skip to the Final Steps section.

If you got any errors, please continue into the Manual Method section.

Manual Method

First, let's clear your cache. You can clean cache by deleting the folders within C:\Users\[Your Username]\AppData\LocalLow\VRChat. AppData is a hidden folder, and you may have to enable visibility of hidden folders in Windows Folder Options. The easiest method to find this folder is by pasting this into your Windows Explorer address bar: 

%USERPROFILE%\AppData\LocalLow\VRChat\vrchat

In that folder, delete all folders, but don't delete any text files!

Now, let’s clear VRChat settings (PlayerPrefs). On Windows, open the regedit app and delete HKEY_CURRENT_USER\Software\VRChat\vrchat. Please be careful when editing your registry, this can potentially damage your computer.

Finally, paste the following address into your Windows Explorer address bar:

%TEMP%\VRChat

Delete the vrchat folder in that folder by right-clicking and selecting "Delete".

Final Steps

Once you've done either method, try opening the Properties for VRChat in Steam and choose "Verify Integrity of Game Files" under the local files tab.

Ensure that you are running the latest version of Windows, and that your GPU drivers are up to date. Please note that we do not support the Insider Edition of Windows 10.

If you're experiencing very low framerates, try uninstalling all virtual audio device software. This is software like VoiceMeeter and MorphVox. The drivers included with this software can cause major performance issues in VRChat.

Please whitelist VRChat.exe in your antivirus program and any firewalls you might have running. If you can't whitelist the application (or if it doesn't appear to work), try disabling real-time protection on your antivirus and your firewall while you play VRChat. Don't forget to turn it back on!

A final resort for connection issues can be trying a VPN. VPNs "bounce" your connection off another server, and may skip bad routes that your ISP is forcing on you. Keep in mind most VPN services have a cost, and using a free VPN will result in very slow performance or potentially other issues.

Contacting Support

If you're still having issues, please send our Support team an email with your logs. You can do this by using this form, or alternately you can contact us via email at support@vrchat.com. Here's how to find your logs:

You can find your logs at:

C:\Users\[Username]\AppData\LocalLow\VRChat\vrchat\

You keep all output logs generated in the last 24 hours. They will have a name like this:

output_log_HH-MM-SS_PM.txt

The "HH-MM-SS" indicates at what local time the client was launched for that session.

You can also find your logs by copying and pasting this into your Windows Explorer address bar: 

%AppData%/../LocalLow/VRChat/vrchat

ZIP up all of the output logs that you have. The easiest way to do this is to select all of them, right click, choose "Send To..." and then click "Compressed (zipped) folder". This will generate a ZIP file that you can send to us.

Please attach the output log ZIP to your ticket. Don't copy and paste the contents, attach the text file!

Also, if you have any error folders in your VRChat folder (C:\Program Files (x86)\Steam\steamapps\common\VRChat) please include those as well. They are typically named in a format like this: 2017-08-01_195906Please do not try to send your VRChat_Data folder!

It works best when you ZIP all of the files up. Many problems are addressed by these steps, so we encourage you to follow them closely.
