Try using different methods of working the yarn around your left hand. I have a “standard” method, but some yarns need more or less tension to run smoothly through your fingers, so I adapt.
Different material for needles, different types of needles maybe. I find it easier to knit evenly on circulars. Play around with needle size as well.
Another thing is your “inner tension”. It’s easier to knit evenly when you’re relaxed.
Could you ask another knitter in person?

It’s sometimes easier to spot problems when you watch someone doing the thing.
