I confirm that...

• [X] I have searched the issue tracker, documentation, FAQ, Discourse, and Google, in case this issue has already been reported/resolved.

• [X] I have read "How to Debug Issues", 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.

• [X] The issue can be reproduced on a stable release of Emacs, such as 27 or 28. (Doom does not support development builds like 29+ or any version ending in .50 or .9x)

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.

This bug shows up in the workspaces function as well. Seems to come from this part of +workspace/switch-to

                   (ivy-read "Switch to workspace: "
                           (+workspace-list-names)
                            :caller #'+workspace/switch-to
                           :preselect (+workspace-current-name))

Commenting out the :caller part resolves the problem
