Cannot map physical address 0x1000 — how to fix in SMG CHAMS

This error is almost always caused by active antivirus software or a third-party anti-cheat blocking memory access.

Step-by-step solution

1. Disable Windows Defender and Smart Screen through system settings.
2. Completely uninstall all antivirus programs — simply disabling them is not enough.
3. Remove third-party anti-cheats: Faceit Anti-Cheat, Vanguard, ACE — these are the most common culprits.
4. Check your Windows version — if you have 24H2 or 25H2 installed, you will need to roll back to a previous version as these builds are not supported.
