Recent Emacs on Windows gets errors trying to recursively load during
startup. I'm using prebuilt msix installer from kiennq
(https://github.com/kiennq/emacs-build), and both the ucrt and regular
versions show this bug. I have not built Emacs myself on Windows in a
while, but the kiennq builds are usually solid.

Emacs -Q is OK, but this minimal setup shows the problem:

In $HOME/.config/emacs/init.el:

  (setq load-prefer-newer t)

Then start Emacs as usual. You will see startup taking a lot more time than
usual, and then in *Messages* you'll see many errors like this one:

As you can see, these errors are suppressed in this test case, but in a
real Emacs session,
later on the same errors prevent loading various files, so my init.el
never finishes loading. As an example of that, I get this error with my
actual emacs config:
