Thank you for writing.

This is worse rings. There is something seriously wrong with the yard. The first possibility is that this is due to grubs. https://extension.umn.edu/yard-and-garden-insects/japanese-beetles#:~:text=Japanese%20beetle%20grubs%20are%20pests,southeast%20region%20of%20the%20state

Management is possible but the diagnosis must be confirmed first. Slice off a layer of turf and look for grubs as described in the links above, send me a picture. 

There is a long shot that it could be fungal in which case it will get better. https://apps.extension.umn.edu/garden/diagnose/plant/turf/circular.html

Please send the picture and we can go over the recommendations on how to use the treatments if you have grubs.

The links I sent you have ways to treat this.  Capture an emerging adult.  My guess is Japanese Beetle by odds.  European Chafer is a new arrival.
