Just updated the plugin to this commit 1af4b73 with provided example configurations

  config = {
    shortcut = {

    },
  },

Though I find these lines and not sure if it's the cause of this or not. https://github.com/glepnir/dashboard-nvim/blob/master/lua/dashboard/utils.lua#L87-L93

I do have nvim-web-devicons installed, but this is the first time I run the new dashboard so my MRU list would be nil?
I don't know lua so please have a look.

Thank you!
