setAttributedText crashes with newline in TodayViewController(Widget)

[label setAttributedText: [[NSAttributedString alloc] initWithString: @"\n"]];

will result in an EXC_BAD_INSTRUCTION

Exception only happens when newline is the string, all other strings are fine. Only happens in widget / today view.

(label is a normal UILabel)

Apple, can you fix this? (same code worked fine in iOS 12)
