Ubuntu – Treesitter says "No parser for Lua" after adding lazy.nvim to my config

I reinstalled neovim and followed the suggestions in this video. Lua syntax highlighting worked perfectly fine, until I added the following file lazy.lua file (and a require in my init.lua)

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "https://github.com/folke/lazy.nvim.git",
    "--branch=stable", -- latest stable release
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)


require("lazy").setup("my.plugins")

It is this last line that breaks things. If I comment it out, things work as before. If I leave it uncommented then:

I get this error whenever I open a Lua file:

I get a similar error with vimscript which I also don’t get if I comment out the last line.

Background info: I am on Linux (Ubuntu), and have not added any other things to my .config/nvim folder, apart from a few key remappings. I have never installed treesitter, and the command TSupdate in nvim gives E492: Not an editor command: TSupdate. Yet there is a treesitter directory in my /usr/share/nvim/runtime/lua/vim/.

Here is the output of tree inside ~/.config/nvim:

├── init.lua
├── lazy-lock.json
└── lua
    └── my
        ├── core
        │   ├── init.lua
        │   ├── keymaps.lua
        │   └── options.lua
        ├── lazy.lua
        └── plugins
            └── init.lua

And the contents of init.lua inside ~/.config/nvim are:

require("my.core")
require("my.lazy")

The contents of lazy.lua is file at the start of this question. The contents of core/ is just some minor unrelated keymappings and options changes. The contents of plugins/init.lua is either empty, or the following, both of which produce the error:

return {
    "nvim-lua/plenary.nvim",
    "christoomey/vim-tmux-navigator",
}

What could possibly explain this? How could adding a require("lazy").setup("my.plugins") suddenly break the parser?

EDIT:
running :checkhealth inside vim gives the following:

    Neovim doesn’t like it when it can’t access language parsers for a few languages.

    According to the docs, lazy.nvim "resets the runtime path to $VIMRUNTIME and your config directory". That renders the builtin parsers unreachable. The solution would be to either turn this default setting off or to install the required parsers with the nvim-treesitter plugin.

    Here is how I do it:

    local opts = {
  ensure_installed = {
    'c',
    'lua',
    'vim',
    'vimdoc',
    'query',
    'markdown',
    'markdown_inline',
  },
}

local function config()
  require('nvim-treesitter.configs').setup(opts)
end
return {
  'nvim-treesitter/nvim-treesitter',
  config = config,
  build = ':TSUpdate',
}

    Had the exact same problem, installing the nvim-treesitter plugin as mentioned by Worm solved it.
