It indicates that system('git --version') returned an empty string, but I'm not sure how that can happen. It could be a bug of neovim. How often do you see the error?

[nhooyr]

@junegunn not too often, it comes and goes.

[junegunn]

Okay, I noticed vim-plug was repeatedly checking the git version. (There was an invalid assumption that Vimscript will short-circuit the expression computing the default value for get() function.) It's a harmless bug but I fixed it and it should definitely help in this case. Please upgrade your plug.vim.

Great, thanks.
