Teams no longer allowing me to share a screen, (Offers to shareWindows only)

[Nathan45]

I have Microsoft teams at work, for several months I used the share screen option in teams to help train.  Recently something changed, when I go to share content in teams, instead of a option to share my screen/and or application, it only offers to share windows.  I've attached a screen shot.  I don't think I've made any changes.  Any help would be appreciated.

@Nathan45 it would look to me that an administrator has changed the meeting policy that applies to your account so the full screen sharing isn't allowed.
