Media Library Non Responsive

I am using the Accesspress Lite theme, which has worked well until recently… cannot pin point the date.

However, my Media Library has just stopped responding… it just spins.
Then after several minutes, I get a blank page.

I have used the media library before using this theme, but doesnt seem to be working any more.

The only real plugin i am using is WP-ShowHide and have tried deactivating it, but didnt help.

Any thoughts or insight would be greatly appreciated.
