Heroes V и Windows 10

The game runs unstably on Windows 10. I feel like Windows is constantly messing with something in the registry, because the game crashes permanently with different compatibility settings. For example, if I check the box "Disable fullscreen optimizations," the game works. After a few launches, it starts crashing when loading the intro. Okay, I remove the fullscreen optimization setting, and it crashes. I put the fullscreen optimization setting back on, run it as administrator in compatibility mode for Windows 7, and with application scaling override enabled – it works. I launched it a couple of times, and it starts crashing again. This happens constantly. If anyone knows how to fix this, please let me know.
