I had some success getting into the database
I'm running Windows 10 with Access 2016. When I opened the database, it seemed to hang, so I hit Ctrl-Break to try to exit. A message box came up saying I could not exit, but eventually the standard message bar appeared warning of macro content. When I enabled that content, the splash screen main menu appeared and I could run the application.
As far as viewing the objects in the database, I could do that too if I held down the SHIFT key while opening the database. There was a navigation panel minimized on the left, but when I clicked that, all the objects became available for examination.
I hope that helps you.
