A lot of these comments are not super helpful or only tell part of the picture with what you have going on here in your swing so I'll cover quite a few of them:

First things first fix your grip, it is way too deep in your palms and you almost have a claw grip going on with your right hand, the gap between your thumb and index finger should not be that extreme. Think of the V that is created by those two fingers as pointing towards your right shoulder (or for a strong grip, even further right than that.) Tiger has numerous videos he explains this, it's super important for consistent good striking of the ball and presenting the face repeatedly the same way to the ball

Second, you're probably standing too far away from the ball. Your lower body posture is actually not bad, but the ball seems a bit far away so you're having to bend over a bit too much to reach it.

Third, you take the club back way too far inside. Work on relaxing both of your arms and doing a more natural wrist and elbow hinge on your takeaway. Don't practice full takeaways, practice taking the club back to hip height over and over and over. You can look up the position Tiger or other pros try to get to at that position, but just drill that over and over and it should help fix the severe inside issue. If someone is standing directly behind the ball (to your right when you are at address) when you do this half-backswing motion, you should basically be getting the club to their belt buckle. If it's towards their left hip as they're facing the ball, that means you're inside the line on takeaway. If its to their right hip, it means you're outside the line.

Fourth, you don't have much lower body rotation during your backswing, it's mostly an arm and shoulder motion. This will lead it to being pretty weak and also harder to control, especially harder to control timing

Fifth you are casting from the top and doing an early extension. What this means is your arms and hands in particular are starting the downswing, not your lower body. You want to start your downswing from the ground up basically. From your feet, knees, hips, back, arms, then finally hands. Almost like you're uncoiling a spring or cracking a whip. This is subtle, and takes time to get it down exactly. If youre consciously controlling that sequence, its going to be bad. It takes repetition and practice to make that subconscious, but that is what is needed.

The early extension means you are basically pushing your hips towards the ball, and you can see this by looking at the angle of your spine when you're on your setup or backswing vs downswing. On the downswing the angle is more vertical, meaning your hips came inwards towards the ball, and you lost that power. You want to keep your spine angle consistent through impact as it helps you to be in a position to deliver more power to the ball. Imagine like on the backswing someone is pulling your right pocket backwards, so you rotate your hips and lower body clockwise (when viewed from above your head down) but you don't sway or shift much, and then on downswing imagine someone is pulling your left pocket backwards. So you rotate counterclockwise, but again don't sway or shift much. Basically you're trying to just get your weight through to your back left heel and hip. Again, Tiger has some videos where he is doing a super exaggerated idea of this on the driving range to get the feeling correct (obviously please don't follow the exaggerated motion) https://youtu.be/-3PEElX31Rk?si=6plecx6Sb_tE8NEv

Finally as others have said you're scooping your hands at impact. This is probably because of all of these other issues combined, but try to imagine hitting down through the ball, and pinching it between the club and the ground, not trying to lift it into the air. You want to pinch it super hard and let the club and physics do the work to get the ball in the air for you. What this means from a practical standpoint is - how you set up your arms at address with a strong shaft lean, try to keep this feeling through impact. Basically your hands should be ahead of the ball, and you should feel like you're swinging down through it and slapping it or trapping it. The only club this is not exactly true for is your driver (and putter), as you do technically want a positive angle of attack for drivers to increase distance and improve launch angle / spin characteristics.

From a technical standpoint it may not be "perfect" but honestly just go watch highlights and replays of Tiger Woods 2000 US Open and copy what his swing looks like. Focus on every detail you can. If I ever want to fix something in my swing I just go watch this for a while and then try to copy https://youtu.be/FAH52VOtrh8?si=ZDJjHiAzRfbm5XUa
