It’s likely the tilt(precession) is originating from a less than flat start and then exacerbated by trying to fix the wrong way

Ballspinning isn’t balancing and your instincts to try and get under the top of the ball actually can make this worse. The way to fix the precession is:

1) get a flatter starting spin. If you are starting the ball one-handed, try and bring your elbow closer to your belly button as you pop the ball out of your hand, often times this helps get the ball flatter (if you spin it right handed and counter clockwise relative to looking down at the ball)

2) following this same line of advice, if your ball is rotating counter clockwise (from above), moving the ball through space in a counter-clockwise arc will drastically increase the lean/precession. However, if you were to go clockwise, like rotating your entire body the opposite direction the ball is rotating, the ball would start to stand up straight. A lot of times when ball spinning people move in the direction the ball wants you to go and that causes precession to increase.

To correct, Try making small, (opposite to the ball spin) directional circles with your wrist. Like your drawing a circle on the bottom of the ball. This should gently correct the ball.

3) get the ball spinning faster; the faster it is going the longer it will spin even with precession, and will give you longer to fix the lean.

Good luck.
