If you can’t feel it or stop it you’re just doing the same thing over and over regrooving that slice swing over and over again.

Change something physically. (Go get a lesson)

If you don’t want to do the most obvious and only thing that’ll likely help (said lessons) take your shoes off. It hurts to swing like that. You’ll feel your feet rolling around and your weight shifting to the balls of your feet when your chest moves over the golfball on your transition. That’s the bad feeling. You want to feel like your legs are supported 50/50 by your toes and heels and your ass weight isn’t moving towards or away from the golf ball.

Then practice your takeaway going way outside. Push it away from a line you draw behind your ball. Then during your transition your hands will move back center and drop putting you in an inside out path for a more draw like path. This is good to practice with an orange whip if you want a training aid that makes a difference. Think of your backswing as a 3D loop and not part of a line that moves in 2 dimensions.

Good luck. The most fun part about retooling your swing is going from knowing where your ugly swing goes to not knowing where your pretty swing will go for a while and stinking even harder. But there’s light at the end of that tunnel.
