Player does not have access to workshop

Created an infection custom game on the console and had my party of 6 join. Everyone could join and play except for one who tried and failed to join with the error message in red: Player does not have access to workshop. When we started with her in the group, I could not even create the game at all. I would enter the preset for infection then get the same error message. Thoughts on what this means?
