High squats can be harder on the knees.
You’re also doing what I call an “accordion squat”. People have lifted ridiculous weights like that, but many people get knee and/or back issues from it.
My suggestion is move out your stance a bit, sit back more, and push your knees out hard. That would be the more moderate approach.
The more extreme approach would be to learn how to Box Squat ala Westside and just work that for a while to give your knee a break and enforce the above cues. You have your entire life ahead of you so even if you hate box squatting like that you might learn something from it and it would only be for a few weeks.
