Fixed Font Upload Issue
This fixed an issue we were having where a valid font type wasn't uploading. Thank you.

Allows .ai file uploads now
After trying every kind of edit recommended in StackExchange to wp-config & functions.php, adding another plugin (WP Extra File Types), looking through log files, being on the phone for an hour with WP Engine, Gravity Forms pointed me to this, and instantly, the file upload for adobe illustrator files worked. I tried disabling WP Extra File Types, but apparently that is still required.

Excellent for adding support to new image file formats
Excellent plugin. Even if the description doesn't say it, this plugin allows AVIF file uploads in WordPress in two steps: – Add functions.php support for AVIF mime types (in child theme if possible): easy procedure with lots of tutorials available. – Install "Lord of the Files" Now you can upload AVIF in WordPress Media manager. To the authors: Thank you! The plugin description does not mention AVIF or other new image formats. It would be useful to a lot of users!

I was skeptical at first
WordPress was falsely detecting a perfectly valid MP4 file with the "Sorry, this file type is not permitted for security reasons" whereas it had no problems letting me upload other MP4 files. I was told that this plugin has a decent chance at solving that problem and to my surprise it did!!! Nice work on the plugin guys. Job well done solving WordPress' own faults.
