Thanks Eli. I could now isolate the problem by copying my big init.el
bit by bit. Here is the file that reproduces the issue. It is the
combination of the modus-theme, org-mode and the external package
org-mime. If any one of the blocks is disabled, Emacs works fine.

Note: I am using use-package for managing external packages.
