Unable to access media library in grid view or to insert using cornerstone

I am currently unable to view or insert media via the native WP media manager in either cornerstone or in the WP dashboard. I can see in list view so I have been copy and pasting and using the add url function in Cornerstone.

I have cleared the cache and purged the server side elements and still nothing has changed. Further, I have disabled all plugins - oddly enough I disabled and deleted Cornerstone but I’m still somehow able to edit using it. I completely don’t understand that one.

Everything is up to date, hosting side is good (It’s never dipped below CPU 60.0) and most of my images are pretty decently sized.

Please see screencast here to illustrate an attempt to place an image while in editing usingCornerstone.:

I have considered utilizing a CDN or another hosting plan/URL to house images to increase site-speed, but not sure about that. Either way, I would like to get the native function fixed and I hope it’s not part of a bigger problem.

I’d love if you can help sort this out. Trying to launch next week, barring a few minor tweaks.
