I've bootstrapped again after the recent hash shortening to ensure my build
is up to date, from commit 1f626e9662d8120acd5a937f847123cc2b8c6e31. The
paths above are unchanged.

Running this from the build dir, I see messages like:

error in process sentinel: Native elisp load failed: "file does not exists",
 "c:/home/ajm/.emacs.d/eln-cache/28.0.50-e2ae3598/hl-line-e67628ec-664ef650.eln"

This suggests that the AOT .eln files are not being found. It should find:

c:/emacs/git/emacs/native/build/mingw64-x86_64-O2/native-lisp/28.0.50-e2ae3598/hl-line-8fa29c14-664ef650.eln

The middle hash (e67628ec vs. 8fa29c14) is not the same - any idea why ?
