  • 2️⃣ Antivirus Block? Add LoL folders to exclusions (e.g., Windows Defender, Norton). Riot Vanguard hates false positives.
  • 3️⃣ Flush DNS: Cmd as admin: ipconfig /flushdns + netsh winsock reset. Restart PC.
  • 4️⃣ Disk Check: Right-click C: > Properties > Tools > Check. Repairs hidden corruption.
