Divi-Modules – Typewriter’s typing engine must be loaded into the <head> of your website pages for Typewriter to work. There are two ways to do this with SG Optimizer:
Turn off the Defer Render-blocking JS setting.
If you wish to keep deferred loading active, you can exclude Typewriter’s typing engine by adding it to the list of excluded files in the Exclude from Loading JS Files setting.
Select the following from the exclusions list: /plugins/divi-modules-typewriter/scripts/typeit.min.js
