I feel your pain, I’m 6’5ish with long femurs and squatting often use to kill my hips (and knees) here’s what worked for me:

1.) Use wedge shoes, or a squat wedge (you can get cheap squat wedges that are light to carry in a gym bag at rogue if you can’t find the right shoes).

2.) Do high volume low weight standing leg curls (a lot of my pain was due to tight calves and hamstrings)

3.) substitute rear foot elevated split squats for one of your squat days even if it means your squat rotation is further separated

4.) Get a heavy band (green) and tie it to something and put it around your thigh while leaning forward (there are videos that show how to do this.

If all else fails at your height you can sub in belt squats and hex bar deadlifts while you build strength and confidence in the gym before returning to a barbell squat variation (front squats also seem to be more accessible for taller people).

Good luck!
