- [X] I have read "[How to Debug Issues](https://doomemacs.org/d/how2debug)", and will use it to provide as much information about this issue as possible.

- [X] The issue can be reproduced on the **latest** available commit of Doom.

### Expected behavior

`C-x b` works and shows the list of buffers

### Current behavior

`C-x b` fails to list buffers, and shows the following error in the minibuffer:

```
[Error in post-command-hook (ivy--queue-exhibit): (file-error "Opening directory" "Not a directory" "/home/armael/.doom.d/init.el")]
```

where `/home/armael/.doom.d/init.el` is the file currently opened.

The `*Messages*` buffer does not seem to include a more detailed error message; I could not get a backtrace to show up either, even after enabling `doom-debug-mode`.

### Steps to reproduce

This bugs seems to only show up with a specific combination of packages. I tracked it down to the following:

1. Start with a fresh doom installation, with the default config
2. in `init.el`, enable `ivy` instead of `vertico`; disable `doom-dashboard`, and disable `(default +bindings +smartparens)`. As far as I can tell, all three changes are required for the bug to manifest.
3. open a file with emacs, for example `emacs ~/.doom.d/init.el`, then type `C-x b`.
