I would check two things:
1) Pull in and lock your clutch. Standing next to the bike manually push the clutch actuator further in by hand. If you can then roll the bike then you simply need to adjust the clutch cable better.
2) If that didn't work, perhaps the clutch is a bit too tight. Keep the clutch lever locked adn remove the right side clutch cover. Take out the retainer screw and loosen the star nut/flower nut 1/2 to 1 turn. Then see if you can roll the bike.
Try that and see if the problem is fixed. There are a couple other options after this but I don't want to confuse you or suggest you start messing with things that might not need to be touched.
