In fact, no plugin is found.

When building nvim from my old unstable version, which still has nvim 0.5.0, it works all fine. So the issue is the update of neovim to 0.5.1 as far as I can see. @manveru @rvolosatovs @Ma27 (neovim maintainers) @gebner (neovim 0.5.1 updater)

This is actually related to #154299 as far as I can see

See #154299 for solution.
