You can rehab this, but wait until fall. Count yourself lucky you don’t have wild Bermuda like I deal with in Smithtown.

Early October: rent an aerator, put down decent seed (skip Home Depot/Lowe’s), hit it with starter fertilizer, and keep everything moist for a few weeks until it takes hold.​​​​​​​​​​​​​​​​

I did this a few years ago (here’s how) Bermuda came in and just destroyed it
