How to Restart Valorant Game Client: Error Code 43 and 12
Restarting the game client is just a fancy way of saying to restart the game. Error 43 and 12 are related to issues with the game client. Close out of the game either by Alt+F4 or using the task manager. Reload the game and your problem should be solved. Make sure your game is updated to the latest version. You might have to do the same with Vanguard as well.
If it hasn't been fixed, close out again and run the application as Administrator. If that doesn't work, restart your computer. If restarting doesn't work, the last thing you can do is to uninstall the game and reinstall it.
Sometimes Error 43 is due to a time out. Some players have discovered that spamming WASD can get you in, as the servers will still read these inputs and not time you out. It's a weird fix that might help you out if restarting doesn't work.
Other times, it make be due to your internet. Restart your router or switch to a different connection type.
