Failed to run `config` for indent-blankline.nvim - attempt to call field 'iter' (a nil value)

Problem

I'm sorry if this is somehow not a bug from this plugin, however this is my best guess (I'm using kickstart.nvim).

Whenever I open nvim, I can see this error message: It worked just fine a couple of days ago, I did not change a thing since then.

Steps to reproduce

Minimal config

return {
  { -- Add indentation guides even on blank lines
    'lukas-reineke/indent-blankline.nvim',
    -- Enable `lukas-reineke/indent-blankline.nvim`
    -- See `:help ibl`
    main = 'ibl',
    opts = {},
  },
}

Steps

Open neovim
Run :Lazy
Sync plugins

Expected behavior

I should not see the error message when opening neovim

Neovim version (nvim -v)

0.9.5
