Hoping to consolidate the various fixes that are available into a single post so users can refer to this list and begin basic troubleshooting


Note that you should be trying ALL of the fixes in this section. These are general troubleshooting tips that should be attempted regardless of your underlying issue.

Run A Full Windows Update

Ensure your OS is fully updated by manually running a Windows Update

Ensure Your Video Drivers Are Up To Date

Ensure you're running the latest drivers from you vendor

Intel Drivers

Note: Do NOT use the Intel Driver Update Utility to update your Intel video card drivers, make sure you download them directly. That tool is somewhat unreliable at identifying some older hardware.

You may need to uninstall your existing drivers from your vendor, reboot, and install the Intel drivers

Apple BootCamp Drivers

Perfom a Clean Uninstall of AMD Drivers

Its possible you may still have graphical issues wiht some drivers. Doing a full uninstall of your existing AMD drivers may help

Download this utility, run it, then reboot your system. Then proceed to install the latest drivers from AMD

Perform a Clean Uninstall of Nvidia Drivers

  • Download this utility
  • Uninstall your existing drivers
  • Reinstall the latest Nvidia Drivers


Laptop users should force their Nvidia/AMD cards

Use the Nvidia Control Panel or AMD CCC to force the game to use your built in GPU instead of the Intel one

This guide should help you depending on your video card:

Disable or Move OneDrive

OneDrive has a tendency to steal focus/permission for your "My Documents" folder causing all sorts of issues especially with save games. Try disabling OneDrive on your "My Documents" folder

Disable or Whitelist Crusader Kings 3 In Your Anti-Virus

Anti-virus can cause issue or conflicts with the game. Please refer to your anti-virus documentation as to how to whitelist Crusader Kings 3 in your program. Note that 'heuristic' or '0-day detection' modes are especially problematic and may be a separate component from your standard anti-virus scans, so ensure you white list it in there as well

Disable Audio Enhancement Tools

Some Audio Enhancement tools can cause issues. Try disabling them. They go by various names depending on the vendor
  • Nahimic (installed on MSI laptops)
  • Sonic Sound 2 (installed on Asus laptops)
  • Sonic Suite
  • Razer Chroma (and possibly Synapse) - note your headset will still be usable

Click PLAY instead of RESUME From The Launcher

Its possible your existing save game is corrupted and clicking "Resume" causes the crash due to your corrupted save game (expecially when combined with the steam cloud issue above). Thus try clicking PLAY from the launcher instead.

Check if MS Security is Blocking App

  • Open Windows Security
  • Click on Virus & threat protection
  • Under "Ransomware protection," click the Manage ransomware protection option.
  • Click the Allow an app through Controlled folder accessoption.
  • Click the Add an allowed app button.
  • Click the Recently blocked apps option
  • Click the + (plus) button for the app you trust and want to allow.

Unplug Controller Or USB Peripherals May Cause Issues

Try unplugging any controllers such an xbox controller

Also Some esoteric/odd USB peripherals may cause issues. Try unplugging an odd USB peripherals and see if that helps

Remove Overclock On Video Card

Some reports that overclocks on your video card can cause instability in the game. Disable any video card overclocking.
