(can also set open_automatic and it will apply to help window)

Expected Behavior

No error

Minimal example file

No response

Minimal init.lua

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
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",
    lazypath,
  })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  {
    "stevearc/aerial.nvim",
    config = function()
      require("aerial").setup({
        -- add your aerial config here
      })
    end,
  },
  {
    "nvim-treesitter/nvim-treesitter",
    build = ":TSUpdate",
    config = function()
      require("nvim-treesitter.configs").setup({
        ensure_installed = { "c", "lua" },
        auto_install = true,
        highlight = { enable = true },
      })
    end,
  },
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here

Additional context

No response

Some amount of this is to be expected. If you close the help window while your cursor is in the aerial window, no autocmds are dispatched so we have no way to know that the window was closed. If you then use <CR> or some other keybind to try to jump to the symbol, there will be an error.

I assume that you have autojump = true set in your config, though it is not present in the minimal config provided. The one thing that could be improved is we could silence the autojump errors when you move your cursor around an orphaned aerial window.
