Here's what I get:

Case 1:
Debugger entered--Lisp error: (wrong-type-argument stringp (require . info))

The way to reproduce case 3:
1. cd && mkdir backup && mv .emacs .emacs.d backup
2. add following codes to ~/.emacs

(require 'package)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
(package-initialize)

(provide '.emacs)

3. Open emacs

  > M-x package-list-packages

  After the package list was refreshed, install yasnippet & yasnippet-snippets

  > M-x package-install ENTER yasnippet ENTER

  > M-x package-install ENTER yasnippet-snippets ENTER

4. Delete package configration from ~/.emacs, only keep this line:
   (provide '.emacs)

5. Exit emacs

6. Delete folders, only keep yasnippet-20200604.246 &
yasnippet-snippets-20200802.1658
  $ rm -rf ~/.emacs.d/auto-save-list ~/.emacs.d/elpa/archives
~/.emacs.d/elpa/gnupg ~/.emacs.d/elpa/s-20180406.808

7. Now open emacs to edit a .org file:

  $ emacs

  > C-x C-f

  > Find file: ~/ex.org Enter

8. You can see the error in minibuffer:
  File mode specification error: (wrong-type-argument stringp (require
. finder-inf))


My emacs version: GNU Emacs 27.1 (build 1, x86_64-apple-darwin18.7.0,
NS appkit-1894.60 Version 10.15.6 (Build 19G73)) of 2020-08-12

alias emacs='/Applications/Emacs.app/Contents/MacOS/Emacs -nw'

Case 3 cannot be reproduced in Emacs v26.3

Thanks
