Modrinth App

You should ALWAYS make backups before uninstalling.

As with any other piece of software, updates may go wrong for many reasons, including but not limited to: the launcher, the hardware, your custom configuration, the mods you added... and, rarely, FO as well.

1. Open the Modrinth App

2. Click on the Library

3. Right-click on the FO instance

4. Click on Delete

5. Click on Delete
