3️⃣ Update Java and Launcher

Minecraft 1.21+ demands Java 21. Download the latest from Oracle or use the bundled version:

2. Update launcher: Help > Check for Updates.

4️⃣ Network and Security Tweaks

Firewalls hate Mojang sometimes:

• Add exceptions for MinecraftLauncher.exe and javaw.exe in Windows Defender Firewall.
• Disable VPN/proxy temporarily.
• Flush DNS: Command Prompt (admin) > ipconfig /flushdns.
• Try mobile hotspot to rule out ISP issues.

If antivirus (e.g., Norton) is aggressive, whitelist Minecraft folders. Gamers swear by this fix! 👏

5️⃣ Advanced: Reinstall or Manual Download

Last resort:

1. Uninstall via Control Panel/Add or Remove Programs.
2. Delete leftover .minecraft folder.
3. Redownload installer from launcher.mojang.com (pick your OS).
