If you mean Minecraft mods , the usual fix is to remove the mods from the game’s mods folder and then launch the game again. If that does not work, you can also remove the mod loader profile or verify the game files so the default version loads cleanly.

Fast steps

  1. Open your Minecraft folder.
  2. Find the mods folder.
  3. Delete the mod files inside it, or delete the whole folder.
  4. Restart Minecraft.

If you use a launcher

  • In the launcher, go to Installations.
  • Remove the modded installation or mod loader profile, such as Fabric or Forge.
  • Then open the regular unmodded version.

If you do not use a launcher

  • Press Windows key + R.
  • Type %appdata%.
  • Open the .minecraft folder and delete the mods folder there.

If mods still show up

  • Use the game’s file verification option if it has one.
  • Reinstall the game only if the mods keep coming back.
