Backtracing variable UIBezlerPath : What to do?
I'm getting this Error when i setted the Backtracing Variable...

This Code is causing the Error for sure:
UIBezierPath* ovalPath = [UIBezierPath bezierPath];
    [ovalPath addArcWithCenter: CGPointMake(CGRectGetMidX(ovalRect), CGRectGetMidY(ovalRect)) radius: CGRectGetWidth(ovalRect) / 2 startAngle: 180 * M_PI/180 endAngle: 0 * M_PI/180 clockwise: YES];
    [ovalPath addLineToPoint: CGPointMake(CGRectGetMidX(ovalRect), CGRectGetMidY(ovalRect))];
    [ovalPath closePath];
    
    [UIColor.grayColor setFill];
    [ovalPath fill];

CGContextSetFlatness: invalid context 0x0. Backtrace:
