Reload last session introduces errors in v3.0.0.-pre

### I confirm that...

- [X] I have searched the [issue tracker](https://github.com/doomemacs/doomemacs/issues), [documentation](https://docs.doomemacs.org), [FAQ](https://docs.doomemacs.org/-/faq), [Discourse](https://discourse.doomemacs.org), and [Google](https://google.com), in case this issue has already been reported/resolved.

- [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.

- [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

I can't get emacs-plus 28 to work right on my system (Monterey) so 29 is the best I can do. I'm checking the box because the form won't submit otherwise.

- Edit a file
- Save it
- Quit Emacs
- Come back later and open Emacs
- Use `Reload last session`
- Expect last session to be loaded

### Current behavior

- Instead of last session being loaded, I get this error:

```elisp
let: Invalid read syntax: "#", 167, 103
```

which refers to the `#` in the following context of the `autosave`

```elisp
(mouse-2 . #)
```

### Steps to reproduce

- Edit a file
- Save it
- Quit Emacs
- Come back later and open Emacs
- Use `Reload last session`
