Indeed the tone...
We all encounter issues at some point but it's no reason to rage quit over. What you should do is consider what actions you've taken with the game recently that may have caused this issue. Have you installed any new content? Or tampered with the files? Created maps? Etc.
In cases like these sometimes it best to simply back up your most important files like presets, maps, and screenshots and uninstall the game. After uninstalling return to the Feral Heart main folder and delete it. After this is done you then should reinstall the game and it should run just fine.
