Gearbox - does it need a new clutch / synchro mesh or full rebuild?

Bought a 2007 197 with 52k miles in august 2020. I use it ( gently) every 4-5 days.... now it is hard to get the car into any gear from cold but once it gets going, it’s fine.... any ideas and is this a quick / cheap fix or a full rebuild? ( the clutch pedal can stick halfway down also).
