Hi Jack,

thanks for replying!

The error does not happen using "emacs -q" (built-in package: org 9.3). I haven't tried with the git version yet. i will and let you know.

Cheers,
Sebastian

I'm unable to reproduce this behavior on emacs 27.1 and git
master. Fontification and export work fine with this code block for me.

Does the error still happen when you use emacs -q ? Or if you use git
master?
