When I open Stadia in Chrome, I am unable to open anything unless I refresh the card.
Also, when launching the game I get the loading screen indefinitely.
Not quite sure what you mean by "card" but if a game won't start the first time in the Chrome browser, I would recommend making sure all extensions, ad-blockers, etc are turned off or try launching incognito mode to see if that solves your issue. Otherwise, the community probably needs more details about your setup to provide any further advice.
