I downloaded the save file from the website, the game starts to load - that screen with the leader appears, it says ‘loading, please wait’, but then it never loads.
Maybe worth mentioning a player joined the game after it started and surrendered before ever playing a turn.
I am hosting the game and this would be turn 2.
My Civ6 version is a Mac App Store one.
This is the game:
