Media Library Stops Loading at certain point

Hi Guys,

Please see my issue here; https://recordit.co/4SLW2PFFMn

I have;
– cleared caches (and cloudflare)
– disabled all plugins
– increased php memory limit (which was high anyway) to 512m to 1024m
– confirmed php limit
– contacted hosts who said to post in here because it would usually be a php memory issue

It is always at this point where WordPress fails to load anymore media items.

Hope you guys can help,
Cheers!
