- [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

No issues, no flycheck errors.

### Current behavior

I cloned my doomemacs as `~/.emacs.d.doomemacs` to don't mixup with my main config. Then installed, added some stuff to ~/.doom.d and ran `doom sync`

When I try to edit any file from `~/.doom.d/` I got the flycheck error:

```
Failed to load Doom: Profile init file hasn’t been generated. Did you forgot to run ’doom sync’?
```


However, if I install as `~/.emacs.d` this issue doesn't happen`.

### Steps to reproduce

1. Install doomemacs in a non-default path (ex.: `~/.emacs.d.doomemacs`)
2. Run `doom sync`
3. Open any `~/.doom.d/` file, for instance config.el
