Nagging IT Band/TFL pain

I was doing the 10 (11 actually) Weeks Squat program from Gregg Everett (Catalyst Athletics) and got a nagging it band/tfl pain on week 7, so I stopped squatting for 4 weeks, even bw squats were uncomfortable, I returned today to do some 5x3@60%, but the pain (4-6/10)comeback on the third set, what could I do to get rid of that? The weights don’t feel heavy, but the pain doesn’t let me squat them
