Sunburst shape distorted when saving Illustrator (Version 24.0.3) file to PDF. I have created a sunburst shape in illustrator using a circle shape, then adding a dashed like stroke. The file looks totally fine in illustrator and also when I save it as a PNG and JPG, but when I save it as a PDF the sunburst is distorted (uneven lines). I even sent an illustrator file to a printer and my prints arrived distorted, which means they had the same problem. They are also using the latest version of illustrator. Is this a bug?

The larger file shows the distorted sunburst in PDF (black/white behind girl). The smaller file shows what it looks like in illustrator (and what it's supposted to look like.
