File tree disapears after session reload with persisted.nvim

Description

When I close a session with :q! with Nvimtree open, after reloading the session with SessionLoadLast from persisted, the file tree buffer appears empty.

Neovim version

NVIM v0.9.0
Build type: Release
LuaJIT 2.1.0-beta3

   system vimrc file: "$VIM/sysinit.vim"
  fall-back for $VIM: "/opt/homebrew/Cellar/neovim/0.9.0/share/nvim"

Operating system and version

macOS 12.4

nvim-tree version

Minimal config

local root = "/tmp/persisted"

-- Set stdpaths to use root dir
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- Bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "--single-branch",
    "https://github.com/folke/lazy.nvim.git",

vim.api.nvim_create_autocmd({ "VimEnter" }, { callback = open_nvim_tree })

Steps to reproduce

1. Exit neovim with :q! and nvim tree open
2. reload the session with SessionLoadLast

Expected behavior

Actual behavior

[alex-courtis]

Sessions and lazy loading interfere with normal order of operations and are very unlikely to behave as expected when you use a VimEnter autocommand, due to the somewhat nondeterministic event ordering that sessions and lazy loading introduce.

Another user had similar issues with auto-session. Perhaps that recipe might help.

Moving to a discussion as the problem appears to be with your configuration.

This will be considered a bug we can fix if you can provide a Clean Room Replicator.

The autocommand works, thanks!

vim.api.nvim_create_autocmd({ 'BufEnter' }, {
  pattern = 'NvimTree*',
  callback = function()
    local api = require('nvim-tree.api')
    local view = require('nvim-tree.view')

    if not view.is_visible() then
      api.tree.open()
    end
  end,
})```
