Temporarily disable your Firewall to test if it allows the game to initialize. Reinstall the Steam Service
For some users, the way Steam handles controller configurations interferes with the game's launch sequence. Right-click the game in your Library. Select > Controller . In the dropdown menu, select Disable Steam Input . Launch the game to see if the error persists. Update DirectX and Visual C++ Redistributables
By following these steps, you should bypass the initialization error and get back to the world of assassination. Most players find that simply running the game as an administrator or verifying the files solves the problem immediately. If you are still seeing this error, could you tell me: What are you using? Are you using any mods or trainers ? Did the game work previously on this same computer?
