Minecraft Error 103 (aka Exit Code 103 or triple digit error) is a launcher crash signaling issues with Java's runtime environment or graphics libraries. It often hits during startup, showing something like "Process crashed with exit code 103" in the logs. Common in Java Edition (1.20+ like 1.21 Tricky Trials), it's tied to LWJGL (Lightweight Java Game Library) failures.
Why "triple digit troubles"? 103 screams "graphics or JVM meltdown!" 😩 No corrupted worlds—just a hiccup blocking your entry. Good news: 90% of cases resolve with simple tweaks. Let's fix it!
Pro tip: Check your latest.log in .minecraft/logs for clues like "LWJGLException" or "Could not create Display."
