### Checklist

- [x] I have searched through the AstroNvim documentation
- [x] I have searched through the existing issues of this project

### Neovim version (nvim -v)

NVIM v0.11.0

### Operating system/version

Linux

### Terminal/GUI

Wezterm

### Describe the bug

Pressing leader-e to open the explorer causes nvim to quit

### Steps to Reproduce

Add

```lua
{ import = "astrocommunity.split-and-window.edgy-nvim" },
```

to `community.lua` then press leader+e a few times to toggle the sidebar

### Expected behavior

It doesn't crash

### Screenshots

_No response_

### Additional Context

_No response_

### Minimal configuration

```Lua
-- save as repro.lua
-- run with nvim -u repro.lua
-- DO NOT change the paths
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "runtime", "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
-- stylua: ignore
vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", "--branch=stable", lazypath })
end
vim.opt.rtp:prepend(vim.env.LAZY or lazypath)

-- install plugins
local plugins = {
{ "AstroNvim/AstroNvim", import = "astronvim.plugins" },
{ "AstroNvim/astrocommunity" },
{ import = "astrocommunity.split-and-window.edgy-nvim" },

-- add any other plugins/customizations here
}
require("lazy").setup(plugins, {
root = root .. "/plugins",
})

-- add anything else here (autocommands, vim.filetype, etc.)
```

Start by running the provided repro.lua with the astrocommunity.split-and-window.edgy-nvim import, then reproduce the crash by pressing leader-e repeatedly. Inspect the plugin specification referenced from community.lua and compare its behavior across sidebar toggles. Done means the explorer toggles without causing Neovim to quit.
