If you look closely there's an area of what I'm calling white-digitial-ants showing up between 2 areas of the picture that were impacted by two different brush adjustments. Is it it due to over-sharpening, clarity? All suggestions welcomed. Picture from Antelope Canyon, Utah.
This is at the bottom left of the photo between the lighting area and the darker area. All suggestions welcomed.

The light striped area is showing evidence of selection exclusions (small areas not included in a selection), and it's not just along that edge. The exclusions are caused by the brush not including everything in the selection, and that can happen when Auto Mask is selected. It's happening most noticeably along that edge.
One possible answer is to deliberately overrun the edge with Auto Mask switched off, then come at the edge from the other side in Erase mode with Auto Mask selected.
In addition to that, you can go over the selected area with Auto Mask switched off and no feathering for the brush. You then go close to the edge of the area to be selected, but overrun the edges only in the places where you're having problems with exclusions. Then you finish off the rest of the edges from within using Auto Mask. You can also use the same technique in Erase mode if the Auto Mask is causing the Erase brush to leave exclusions.
When you're using a brush right up to an edge with Auto Mask turned on, I find that a hard brush (no feathering) is more likely to force an unwanted overrun (going over the edge) than a brush that has a small amount of feathering. Plus you should adjust the brush size to suit the size of the indentations and contours of the edge that you're working to. A large brush making large incursions into an unwanted area is more likely to force an overrun than a small brush that makes only small incursions into the unwanted area (an unwanted area is any area outside the intended selection).
I suspect that applying sharpening before making your selections increases the likelihood of getting exclusions when using the Adjustments brush with Auto Mask activated.
I hope there's something there that helps.

Do you have Photoshop? If so, zoom in and try the healing brush.
It looks a lot like fringing, so you could try the techniques in this video:
