Some (low-level) software on your system performs a disallowed memory operation. Please try to close all unnecessary programs while playing the game. Recently, we are seeing an increased amount of reports from players using the latest version of “MSI Dragon Center” and “MSI SDK”. Please completely uninstall those from your system and reboot to solve the issue. Alternatively, you can also try updating your Windows 10 to version 2004 or higher, as that seems to fix the issue as well. If that doesn’t help please perform a full repair reinstallation of Windows.
