Sometimes when you are tacking over uneven joists and the edge of the board is trying to pull itself up to a higher joist the board edge just cracks and splits as you try and get the screw flush to the board.
you can overcome this by making a SHALLOW countersink hole using just the drill bit of the screwgun.
spin the drill bit into the board and rotate the screwgun in a quick wide circle....alls you want to do is create a divot wide enough to accept the head of the screw. ideally no deeper than the head of the screw.
you can also do this on the occasion where you find yourself having to screw in at an angle instead of straight upward.
you can buy a handheld cheap bradawl type countersink device but i find the drill bit quicker and easier.
