ResolveImageConfig takes 70.1s to complete

Reproduce the report with the supplied Dockerfile, Docker Engine 23.0.1, and BUILDKIT enabled, measuring the resolve image config step. Trace the image-config resolution path to identify why the cached Dockerfile frontend takes about 70 seconds; done means repeated builds avoid that delay and the behavior is covered by an appropriate regression test.

I enabled BUILDKIT, after a successful build image, the first step of building again does not use caching and is very slow.
resolve image config takes 70 seconds!
