Images not building after upgrade to Docker for Mac 4.4.2 (73305)

Oh… I see. I forgot about that part of your original message

I will bookmark this topic and when I have time to play with it, if I can find something out, I will come back. Until that if you really want it to be fixed, so you can use buildkit again, you should open an issue on GitHub or maybe just comment on the one I shared above.
