  • Check the version of Minecraft and then check which Java JDK/JRE version is required for that version, check which version of Java you have. If not the same, try to install that same version of Java.
  • Try to repair the game using the launcher's repair function. This may fix the corrupted game files.
  • If you did recently add any mods or custom content, try removing them to see if this fixes the issue.
