Discord is one of the best apps that we can use to keep in touch while enjoying cooperative games with friends. It is ideal for sending and receiving messages of all kinds, including creating channels that would be something similar to “forums” but more dynamic. The problem is when we meet the JavaScript fatal error in Discord that prevents us from using the app normally. Luckily, we know how to fix this annoying error.

Fatal JavaScript error in Discord

Run Discord as administrator

Run Discord as administrator.

One of the possible solutions is to simply run Discord as administrator. For this we are going to go to the shortcut and we will right click, in the context menu we will choose “Run as administrator” and we will verify if the error appears.

Run this program as administrator.

In case it stops appearing, we can configure access so that it always runs with administrative permissions and we don’t have to open it by right clicking. For this we are going to right click on Discord access and choose Properties. In the Compatibility tab we will mark the option “Run as administrator” and then click OK.

Delete AppData folder from Discord

Another reason why this annoying error appears, can be due to the application cache. Luckily, it’s pretty easy to flush this cache, we’re actually going to delete it; but no need to worry, a new one will be generated automatically.

We start by opening the Task Manager (Alt + Ctrl + Delete) and make sure that no Discord process is open, the program must be 100% closed.

Next, we’re going to press Windows + R to bring up the Run dialog and type %AppData%, hit Enter. A new File Explorer window opens, we look for the Discord folder and proceed to delete it. We will also permanently delete it from the recycle bin.

Uninstall and reinstall Discord

If the problem persists, we are not left with many alternatives. The last solution is to remove Discord from our computer by uninstalling it. And then reinstall it.

  • We start by opening Settings with the Windows + i key combination.
  • Go to the Apps tab and choose Apps & features.
  • Now we will have to search for the Discord app and press the three buttons on the right side.
  • Click on Uninstall and follow the instructions on the screen.
  • Once we did this, we go to the Discord installation folder and delete it.

To finish, we will have to restart the computer. Once you launch Discord again it will be uninstalled; so we can proceed with re-downloading the executable and installing it again.
