• Disable mods: Create a vanilla profile first.
• Check "Game Directory" path – no special characters!

4️⃣ Antivirus & Firewall Bypass

Whitelist MinecraftLauncher.exe and javaw.exe. Temporarily disable real-time protection – relaunch, then re-enable.

5️⃣ Clean Install for Stubborn Cases

Last resort:

1. Backup .minecraft/saves.
2. Uninstall launcher via Control Panel/Add/Remove Programs.
3. Delete %appdata%\.minecraft.
4. Redownload from official site.
