If you are worried about if you are banned from that game or not, I would recommend getting into contact with the game's staff if applicable to inquire not only about your account's status but your error as well. I don't know if their system allows for it as I've never touched Roblox in mah life lol but it's worth looking into if there isn't a community pool for help about these issues. I hope you can find the issue and get it fixed!
