As indicated in the system requirements, our game does not support laptops that do not have a dedicated graphics card. However, the game may still run on some integrated graphics cards. You will need to disable all "heavy" graphic settings for this. To do this, find and run config.exe in the game folder, click Troubleshooting, and check the "Simplified graphics" option. It may be that you were playing on a laptop with only an integrated graphics card, and everything was working fine, but at some point, the graphics card somehow stopped coping. Since we don't change anything in the game, this is a problem with the computer, graphics card, or drivers. However, using the new option theoretically can help. In any case, I remind you that we do not support laptops with only integrated graphics cards. However, we do everything we can to help as many players as possible.
