Rainbow Six Siege keeps crashing
Old drivers, damaged files or background apps
Crashes, freezes and stutter on PC usually come from a system below the requirements, missing or damaged game files, old graphics drivers or apps running in the background.
How to fix it
Check that your PC meets the system requirements for Siege.
Update Windows and your graphics card driver from AMD, Intel or NVIDIA.
Run the game with administrator rights.
Verify the game files in Ubisoft Connect, Steam or the Epic Games Launcher.
Close background apps that may interfere with the game.
