Has anyone else been having problems with the HOI4 game constantly crashing. I've tried playing with both mods (Rt56) and no mods on and I have also performed a clean install but am still suffering from these crashes. I even tried changing from DX11 to DX9 to Open GL but I still ended up crashing. Sometimes it takes a while but HOI4 still crashes. Has anyone else experienced this or know of a solution? Did the game update recently and is this why I am crashing?steamcommunity.com

Methods to Resolve HOI4 Crashing

Restart Your System

If you play Hearts of Iron 4 for a long period of time, your computer may overheat, causing poor performance and forcing your system to shut down the game. System glitches and processes running in the background can also be the reasons.

In this case, you can power off your computer for a while, then restart it and check if Hoi4 can run normally.  

Run HOI4 as Administrator and Disable Fullscreen Optimization

If HOI4 keeps crashing, it may be due to insufficient permissions for the software to run. Once HOI4 is not allowed to access certain files, it may crash. Moreover, fullscreen optimizations can sometimes bring bugs, causing crashing issues.

Step 1: Right-click the HOI4 shortcut and select Properties.

Step 2: Go to the Compatibility tab, then tick Disable fullscreen optimizations and Run this program as an administrator.
