Sometimes, this error can also occur due to connectivity issues. Therefore, ensuring that your internet connection is stable is important.

Open a web browser and try visiting a few websites to confirm your internet connection is working. If you’re on Wi-Fi, try moving closer to the router or switch to a wired connection for better stability.If you encounter any internet issues, try resetting your router by turning it off for 10-20 seconds and then turning it back on.Ensure no other applications (e.g., streaming services, large downloads) are using a large portion of your bandwidth.

Now that we’ve covered basic troubleshooting tips, let’s move on to detailed solutions:

1. Run Steam as Administrator

Running Steam as an administrator can help bypass certain permission issues that may be preventing the game from initializing correctly. It ensures that Steam has full access to modify files and connect to the network without any restrictions from Windows User Account Control (UAC).

2. Adjusting Firewall Settings

Restrictive firewall settings can block Steam’s communication with the servers, which may prevent the game from initializing properly. Adjusting these settings ensures that Steam can communicate with the servers and that no firewall restrictions block the game’s internet connection. This can also resolve connectivity issues that might be causing the error. By adjusting these settings, we allow both incoming and outgoing connections without restrictions. This will prevent firewall restrictions from blocking the game’s initialization and help resolve connectivity issues from the client side.

3. Temporarily Disable Third-Party Antivirus

If you are using third-party antivirus software like Avast, Kaspersky, or McAfee, temporarily disable it. Overprotective third-party antivirus software can sometimes interfere with Steam or the game files, preventing them from functioning properly. Temporarily disabling your antivirus or adding exceptions for Steam and Marvel Rivals can resolve the issue. If your problem is resolved, Re-enable Windows Security and add your game to the Exclusions/whitelist to prevent the antivirus from scanning or blocking its connection. Here’s how:

4. Verify Game Files

Corrupted or missing game files can cause initialization errors. Steam has a feature that allows you to verify the integrity of game files. Verifying the integrity of game files ensures that any corrupted, missing, or incomplete files are replaced with the correct versions from Steam’s servers. This can fix issues that prevent the game from initializing properly, allowing you to get back into the game.
