WordPress not loading

Dear Support,

I have encountered this issue when I am trying to edit my page in WordPress. The site is loading fine when users are accessing it outside. The problem comes when I log in to WordPress and try to edit it using Oxygen. I contacted my hosting support and they said it might be due to my plug in. I disabled all plugins besides Oxygen and it is still not loading. It stuck at the loading page (Please see image attached). Can you please advice what could be the issue? It has been two days and I still cant access my site. Please help. Thank you!
