In this article, we’re talking about Minecraft exit code 1, its causes and what you can do to fix the problem.


What causes Minecraft exit code 1?

How to fix this?

Here are seven fixes you can try out. 

Restart the game

Restarting the game or your PC (or console) is also a good idea. Sometimes temporary bugs in the game won’t let you connect to servers even when online. In such cases, restarting the game or your PC can potentially resolve the Minecraft error.


Update Windows and Minecraft

Updating the game and your OS can also help resolve the issue by eliminating any underlying bugs hindering functionality.

Check out this guide to quickly update Windows or pause updates if it's hindering your game.

Disable Mods

While using mods can enhance your Minecraft experience, they’re also known to add random issues to the game from time to time. If you’re struggling to deal with exit code 1 in Minecraft, try disabling any active mods in your Minecraft installation to see if that resolves the issue. 


Install the latest JDK version 

Before proceeding, make sure all instances of Minecraft and the Minecraft launcher are closed. Then follow these steps. 

Step 1: Head over to Oracle’s JDK download page and download the x64 installer for the latest JDK version (19.0.2 at the time of writing). Install the downloaded installer once the download is complete.
