The Reason behind Valorant Error Code 128

There are many reasons for this Valorant Vanguard Error Code to appear, which we will take a look at one step at a time with each possible solution below. So buckle up and follow the solutions below so you can fix Error Code 128!

How to Fix Valorant Error Code 128

Restart Riot Client

The Riot Client can cause a lot of error codes to appear in Valorant because it is the starting point of the game. So the first simple fix you can try is to restart the Riot Client. Even Riot Games recommends you try restarting the Riot Client first.

To restart the Riot Client, open up Task Manager by pressing Ctrl+Shift+Esc. In the Task Manager, select the Processes tab above and locate the Riot Client. Once you do, select it and click on End task to close off the Riot Client process. You can also end other related game processes and restart Valorant which increases the chances of fixing Error Code 128.

Change VGC Startup Type

The VGC Service is the core service running for Vanguard. So if it does not start up properly from the get-go, it can cause a lot of error codes in Valorant, including Error Code 128. So what you can do is change that startup type of the VGC Service.

To do this, click Windows Key+R on your keyboard to open the Run Dialog. Type in “services.msc” and locate the “vgc” service. Once you do, right-click it and select Properties. At the Startup type option, select Automatic, click on Start and select Apply.
