Could you share a save where the issue occurs for you?
I did some digging and the problem is that they broke their own game. At the start you can choose a play mode. They save this mode in a variable named "Play", which is aYou must be registered to see the linksthat should not be used. URM just exposes their mistake.
There seems to be a way around it, because URM's theming engine exposes the issue. It looks like you have globally set a (non default) theme for URM. So if you clear the theme you've set from withing another game, Life in Alphaville should start fine.
But... this will not guarantee it won't still crash at some point. They still broke Ren'Py itself.
That explains why the previous version without the theming support was working
