This game crashes every 1-10 minutes with "The UE4-Medieval_Dynasty game has crashed. Fatal error!" I've changed my auto save to 5 minutes, but most of the time I don't even have a chance to make it to an auto-save. I've done so many things in the last 4 months to try to fix this but I feel like I've hit my limit. I've been wondering if the most recent update has had anything to do with the crash frequency.

All drivers are updated from all aspects (Lenovo, Nvidia, Windows). I've changed, disabled, and uninstalled antivirus software. I've tried the few game-specific fixes with no help, such as using DirectX 11, changing to windowed fullscreen, lowering graphics. I've also tried running the game exe with compatibility settings for Windows 8, etc., community member suggestions like removing files to verify game files and reacquire, such as C:\Program Files (x86)\Steam\steamapps\common\Medieval Dynasty\Engine\Extras\Redist\en-us deleting the UE4PrereqSetup_x64.exe.

I've also tired many tweaks and fixes, in Windows and Nvidia. I've uninstalled and reinstalled the game and other software. I verify game files after every few crashes. I've done a ton (I've kept a list for Lenovo tech support, too), including doing a clean drive Windows reinstall three times in the past few days. This is currently the only game on my computer with very limited other software installed.
