In my view, Crayon Syntax Highlighter is the best Syntax Highlighter plugin and I installed it from the beginning when I deployed my first WordPress website.
While now it is not updated for a long time and is also not compatible with WordPress 5.
Have to disable it while will keep it in my plugin list and hope one day it could be updated for latest WordPress.
Crayon Syntax Highlighter: WordPress 5.4> Gutenberg – Php 7.4 > compatible
Just now I enabled it again.
