It could be a few things, some you describe, some other stuff up and down your chain.

make sure your abdomen and glutes are tight as you descend, stay upright as much as possible and don’t bend forward to compensate for depth.
most likely if you are working the hips and still have problems, it’s about the parts of the leg lower than the hips.  so ankles, lower leg, hams, quads.
