For steam games, this often means creating a steam_appid.txt or using a specialized "No-EAC" launch option.

Narrow your scan. Instead of scanning 00000000 to 7FFFFFFFFFFF (All), try to narrow down the scan range to the specific memory area of the game module (e.g., game.exe ).

This is the single most important step, as it grants the necessary privileges to access the memory of other processes.
