Contact the team regarding/with/on/about this issue.
Contact the team about this issue and Contact the team regarding this issue are both correct and work regardless of whether the issue is a topic or a problem. You can contact the team about workplace rights or cancer, but you can't contact them "with" those things. You can also contact the team about a bug in their software or about a problem you're having with their software. In the last case, "with" would also be acceptable - though "about" might still be preferable.
Contact the team with this issue works if the issue is a problem whose details will be conveyed to the team. (Compare "if you are the winner, contact us with your name and address" - "with" precedes the information to be conveyed to the team.)
*Contact the team on this issue is wrong. (You could "contact them on an old Nokia phone", but "on" here would mean "using".)
