What should I do if ROB RUN crashes?
Restart the PC, disable overlays and verify the game files.Start simple: restart the computer and launch the game only from your Steam library. Easy Anti-Cheat does not start if you open the executable directly, and the game closes with an error.
Disable overlays — Discord, GeForce Experience and the like: they often conflict with the anti-cheat. Check the antivirus quarantine: if it removed a game file, verify the integrity of the files in the game properties in Steam.
Make sure the computer meets the minimum requirements: 12 GB of RAM, a GTX 1050 Ti class GPU, about 20 GB of storage. If memory is short, increase the page file and close the browser.
If the frame rate drops when you move the mouse, lower the mouse polling rate to 500 Hz or less. The game cannot be run through Remote Desktop — that is a separate error.
If you see a code such as E-0102 or E-0501, look it up in our error table: each group of codes has its own cause and fix.
