Troubleshooting

"Anti-Cheat Error": Disable HVCI/VBS (Windows Security → Core Isolation → Off), update BIOS, disable RGB software (iCUE, Armoury Crate).
High Latency: Ethernet > Wi-Fi. Select **Data Center** manually (MCC: Settings → Network).
Stutter: Shader cache rebuild (delete `%LOCALAPPDATA%\HaloMCC\` / `%LOCALAPPDATA%\HaloInfinite\`).

MCC = classic Halo MP preservation. Infinite = modern live service. Both free with Game Pass. Start there.
