How to fix autoloads in emacs 28?

[XeCycle]

I started using the 28 pre-release branch recently; I simply did an in-place upgrade from 27, with these in .emacs.d/elpa:

helm-20220114.1641
helm-core-20220104.1344
helm-ls-git-20220113.1752
helm-lsp-20210419.2014

After startup helm-browse-project in a git-controlled dir fails with "Symbol’s function definition is void: helm-completion--flex-transform-pattern". Manually evaluating (require 'helm-mode) can fix it. Does not happen in dirs without git, though; not sure whether the problem is on emacs side or helm or helm-ls-git?

My emacs-version says "GNU Emacs 28.0.90 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.31, cairo version 1.17.4) of 2022-01-08".

I created a new git repo for this, and found that an empty git repo does not trigger this problem. So I populated it with some empty files, that's it.

Thanks, confirmed it works now.
