have a good look at the posture spine angles formed here at address. also the difference in the angle between the arms to club shaft.
you can see couple things, you very upright with spine angle so the ways the arms hang to the shaft make that pretty much a straight line. unlike the spine angle & the definite arms to shaft angle in the other image. so little ways posture change plus arms to shaft would be a ways better.

few ways you can shank a ball.
but what's happening in your action is the club moves back away to the inside a little then atop the swing you start down with the upper body hands arms & club working out & over the top some little ways disconnection between arms & body motion. so the clubhead is approaching the ball from outside & swinging a ways leftfield through impact which is presenting the hosel to the ball.
can see what you doing with the sticks put this isn't helping your issue at the moment.
so still making sure feet/hips/shoulders square to target line for now lose the sticks.
instead make use of an empty range basket. put an upturned basket 1&1/2 inches outside the ball. has to be that close.
drill is to make some half swings at 60% speed feeling you move the clubhead straightways back off the ball for the first 8 inches or so then up to the top. this so you don't drag it a ways back inside off the ball.
then feel your back looks to target momentarily as you start down & swing through to just miss the basket. might want to do some practice swings right up close to the basket first before you introduce a ball.
as said previously your is more an over the top shank. so it's the first way the guy is speaking to as to what's causing your shank, taking it back inside then swinging out over the top. you'd put the upturned basket right up close outside the ball instead of the empty box.
Looks a very "armsy" swing, as said posture needs to be more athletic. Your current setup also will give a very toe down/heel up strike, try setting up with sole of the club more natural to the floor. It will feel like your hands are really low to start with but will help with all the other above setup changes mentioned. How tall are you?
first off make sure you looked at addressing the posture at set up. particularly the angle between the arms hands & shaft.
then a drill to help the club go back on line on plane a ways better - so you don't turn it over & drag it inside - but able to get the club head going back straight during the first 8" or so of travel (as said in my earlier post), so the club face more stays 'looking' at back of ball during this first move away.
with that little ways better posture. put a tee in the butt end hole in the handle, at address the tee will point someways around your belt buckle/belly button.
if the club head at address behind the ball is at 6 o'clock.
make the initial move away from the ball with your upper chest/shoulders turning so moving the arm triangle with 'still hands' (so no independent wrist movement) so the tee remains pointing to your midriff until the club head points to around 8 o'clock (hands at this point just around outside the right thigh. so this just a short distance of travel the club head moved maybes 3 feet or so.
repeat till you get the drift of this small first move away so the tee (so butt end of the handle) stays pointing at b.buckle/b.button area with the wrists staying real quiet, so the face of the club stays looking at back of ball over this first 8" of movement.
once you get little ways used to this move away to 8 o'clock. then just continue on to the top of the swing from this point by turning & allowing the 'left thumb' to hinge upwards to point more up to the sky - rather than roll over to point the left thumb back behind your heel line. then the right elbow hinges, complete the turn & you're at the top with the shaft atop your right shoulder.
{although this vid is about something else you'll see the above small drill to 8 with the tee. at around 3' 30" into the vid.}
I've had a few bouts of the unmentionables, but I'm alright now! Try the following. Check your stance and posture, make sure you are not swaying too much or losing your balance (you should be able to hold your finish without falling over), keep your head still and your eye on the ball. Exercises that help are hitting a short iron with a half swing and your feet together, and placing an obstruction, such as an empty shoe box, a head cover or another ball just outside the line and try to hit the object ball without touching the obstruction.
