Hello. Do you have the Steam Overlay disabled? This error can pop up if you have this disabled. You can change this in your Steam In-Game Settings. If you continue having issues, you can also purchase Destiny 2 Silver on our [url=https://store.steampowered.com/itemstore/1085660/browse/?filter=all]Steam page[/url]. If you do, you may have to restart for the Silver to show up.
