I had been playing HOI4 without any issues for years and yesterday, while trying to play HOI4, I received the following error message:

​"An error occurred. The game appears to have crashed or terminated unexpectedly (exit code 3221225595). The issue may be solved by verifying the integrity of your game files and deactivating any mods. If you are using Windows, you may also need to install Visual C++ Redistributable and .NET Framework."

​I have already tried everything to resolve this issue,

​Deactivated all mods, ​Installed Microsoft Visual C++ Redistributables, ​Installed DirectX 12, ​Checked for the latest Windows updates, ​Attempted to bypass the launcher by running the game directly as an administrator (which resulted in 3 different ".dll" missing errors), ​Verified the integrity of game files via Steam.

​Performed a clean reinstall (deleted all folders and reinstalled the game from scratch), ​Disabled and even uninstalled my antivirus, ​Modified the properties of hoi4.exe.

​Literally nothing works, the damn error keeps popping up. Interestingly, I also have Victoria 3, and it runs perfectly fine.

​What should I do now? Is this a HOI4-specific bug? Is there anything else I can try? And finally, is there any chance Paradox will refund my money?
