I'm really not sure. I'm relatively confident there's no problems there on official builds or I'd know by now. If you provide information on what device you were using and how you were running it I could maybe provide some insight.
From the looks of things you were navigating menus while in a specific part of the opening scene that's coded slightly differently between PC and Android, so that could be playing a part, especially if you're using something like joiplay. The "Wait" that's producing the name error is a dialogue choice, not a variable, so my instinct is to say this is a bug being caused by the device than by anything in the code itself. Menu options shouldn't be producing errors like that, it's very basic Renpy.
That's all I can stab at without knowing more information.
