Marked as lens

This think it is an overlap of a yellow star against a distant galaxy. There are other galaxies around the image that are the same blue colour. Usually lenses are a different colour. Also, it doesn't show a hugging curve, though I am sure we will find multiple lenses which mess up the final shape of the lensed galaxies. Hopefully, one of the scientists will correct me if I am being too cautious.

I wouldn't write this one off. The arc like feature could be a companion of the nearby blue galaxy. I think there is also faint blue emission in the center that may be a counter image, but it's very hard to tell without the 'bluer' option in talk. The 'lens' looks physically extended and slightly elliptical, which would rule out a star. The 'hugging' is a small problem but the dark matter and the stars aren't always completely concentric, so it isn't the end of the world.
