I hope you can help me with the following issue I have been experiencing with the Steam client:

- Even though my PC has a stable wired internet connection, the Steam desktop application continuously shows a connection error and fails to launch.
- I have already tried uninstalling and reinstalling the Steam client.
- I also switched to a wired (LAN) connection instead of Wi-Fi, but the problem persists.
- The application neither connects nor opens correctly, despite other internet-dependent applications working fine.

Could you please assist me in resolving this connection issue? I would greatly appreciate any troubleshooting steps or diagnostics you can provide.
