File tree disapears after session reload with `persisted.nvim`

-- Bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",

Steps to reproduce

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

[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.
