I've been experiencing the same issue since yesterday afternoon! I cannot see my developer team in XCode. I can see I have the required permissions on App Store Connect, but when I try to access https://developer.apple.com, my Developer Team isn't linked, and I receive the same error message as Gulden above. "Unable to find a team with the given Team ID '*********' to which you belong. Please contact Apple Developer Program Support. https://developer.apple.com/support" (Team ID removed) Hoping support can provide some answers soon!
