GTA III 10 year anniversary can’t save

I have just completed 2 missions by I can’t save. When I go into a safehouse and try to to save, the screen goes almost completely dark. I can just barely see the list of saves and when I click on the save file I want to overwrite nothing happens. Pressing cancel does nothing either. Pressing the back button on my phone will bring me back into the game, but I still cannot save. Please help!
