If you are seeing “Unable to initialize SteamAPI” and want to fix it, try the following solutions. Let us talk about them in detail.

1] Allow Steam through the Firewall

As it turns out, your firewall is blocking Steam from launching the game as a result of which you are seeing the error message in question. To fix the issue, you can disable the third-party antivirus you have or whitelist the game. In the case of the Windows Defender Firewall, you need to allow the app through it.

This way, your app will always open with the required permissions. Now, open Steam and launch the game that’s giving you the trouble. Hopefully, it will work this time.
