increase you touch point size. Maybe add them manual. One on each side of ring up to oval area. 2mm wide support with .6 to .8 touch points.

Add supports to the side. Not where it is curved but BEFORE the curving starts and than maybe extra where it is actually curving.
Or try supports on the inside of the shank Before the curving stars and then some more where it is curving.

Also are other parts with the same or more height straight? If the bend as well then you need to check if everything is still in place and screws are tight.

I have tried to add supports and bigger tips and different positions. No luck. Always same thing.

I have no problems with other models. This is only one with problems.

Very weird problem. Especially if all other models are good.
You could try to print the ring at an angle. Now it is straight but what if you have it at a 15 degree angle or more. Then the angle is not to much that you need to support the sides. But it might be big enough to solve your problem.

I tilt the ring ~20 degrees or until one edge of the head is straight up the Z-axis. Place heavy supports 0.5mm or thicker for bigger rings (no ball-point). Under Auto Supports, increase the "Support Thickness" to 1.2mm or higher.
You're going to need to support the prongs with ball-point 0.3mm supports but it should print good. I assume that's B9's Emerald resin? If so, it wouldn't hurt to lower the Z-lift speed to 75 because B9 resins are sticky.
