Genshin says illegal tool detected but I'm not running anything

Game closes on launch with an illegal tool detected message. I don't use any mods. Only things running are Discord, an RGB lighting app and MSI Afterburner. Could one of those be setting it off?

It usually isn't a cheat. The anti-cheat flags anything that hooks into the game or reads its memory, and a lot of normal software does that. The usual culprits: - overlay and FPS tools (MSI Afterburner / RivaTuner, some recording overlays) - macro or autoclicker software, including mouse and keyboard apps with macros turned on - anything like Cheat Engine still running in the background, even if you're not using it on Genshin Close those from the system tray, not just the window, then launch again. If it still triggers, restart the PC so nothing is left running in the background, and check Task Manager for anything you don't recognise.
