Thanks for you reply Eli. I think I figure out what’s going on. The `flyspell` also hooked with org-mode load failed by `failed to define function flyspell`. Then all other modes hooked in my org configuration don’t load. 

Sorry for bothering. This issue can be closed.

Thanks

I add several modes hooks to org-mode via `use-package` and `straight.el`. However, it doesn't load
any of them as it did in several previous versions.

Here is my configuration:

```elisp
(use-package org
 ;;:straight (:type built-in)
 :ensure org-plus-contrib
 :hook
 (
  (org-mode . org-indent-mode)
  (org-mode . visual-line-mode)
  (org-mode . ejira-mode)
  ))
```

Regardless of whether `:straight (:type built-in)` is configured or not, the modes that are being hooked
don't load.

AFAICT, you are using :hook incorrectly.  The "Hooks" node of the
use-package manual explains how to use it correctly.  In a nutshell,
:hook is not for adding stuff to the hook of the package you are
declaring with use-package.
