I just completed it tonight with 100% achievements, played it for 69 hours, most of which was in the last few days playing very long game sessions. My PC is modern. I'm on the latest Windows 11 and fully updated. It has a 5800X3D CPU, RTX 5080 GPU, 32GB DDR4 RAM and playing on a 240hz 4K monitor. Hasn't crashed once.
What you need to do first is download the latest versions of your GPU driver, then uninstall your GPU drivers with DDU (display driver uninstaller)in safe mode and make sure the ethernet is unplugged and wifi turned off before you do this so windows update wont automatically install a driver from the internet when you reboot the computer. Then you run the drivers you downloaded before you uninstalled with DDU. This ensures there is nothing conflicting with your GPU drivers from older versions of files and registry entries that may be left behind.
Then i would suggest updating the BIOS for your motherboard.
Once you have done that, go to your CPU manufacturers website (intel or AMD) and download the chipset driver for the motherboard, latest version of course, DO NOT download it from the motherboard manufacturer. They always have the outdated versions.
After you have done this make sure that you update the Microsoft Visual C++ Redistributable runtimes for Windows. Also update the .NET framework to latest versions.
Uninstall the game and delete all the configuration files from the hard disk. Then reinstall the game.
Also make sure that Windows 11 is up to date.
When the game crashes check the event log in windows to see what is causing it. ChatGPT will help you diagnose anything showing up there related to the game.
The reality is that it's not working because something on your computer is not configured right or you have some form of hardware instability. If you run software that puts any sort of overlay onto the game window, shut that program down and make sure anything you don't need running in the background is shut down in task manager .
The game works fine you just need to figure out what it is on your setup that is causing the crash.
