Bug: lualine is not showing in neovim nightly

Self Checks

[x] I'm using the latest lualine and neovim nightly.
[x] I didn't find the issue in exsisting issues or prs.

How to reproduce the problem

Install lualine.nvim using vim-plug. Use the minimal configuration provided by the documentation:

require('lualine').setup{}

Actual behaviour

The statusline is not showing after installation.

Expected behaviour

Statusline shows as expected.

Aditional information

I noticed that when running :checkhealth lualine suddenly appears during the checkhealth process, and dissapears a few seconds after. I tried disabling my colorscheme and other plugins that might be interfering with the plugin's behavior, but got not luck at all. I'm attaching my dotfiles at the bottom of this issue just in case. My current neovim version: NVIM v0.5.0-dev+1233-g82ac44d01

Minimal config to reproduce the issue

I'm using the vimrc configuration provided by the documentation.

let g:lualine = {
    \'options' : {
    \  'theme' : 'gruvbox',
    \  'section_separators' : ['', ''],
    \  'component_separators' : ['', ''],
    \  'disabled_filetypes' : [],
