AUCTeX documentation[1] has the following instruction:
,----
|  -- Command: TeX-fold-buffer
|      ('C-c C-o C-b') Hide all foldable items in the current buffer
|      according to the setting of 'TeX-fold-type-list'.
| 
|      If you want to have this done automatically every time you open a
|      file, add it to a hook and make sure the function is called after
|      font locking is set up for the buffer.  The following code should
|      accomplish this:
| 
|           (add-hook 'find-file-hook #'TeX-fold-buffer t)
`----
Please try this instead of adding `TeX-fold-buffer' in `LaTeX-mode-hook'.
