I can start the game no problem but I can't read any of the words on the start screen literally I can't make out any of the words out on my windows laptop and when I load a save same thing happens.

Interesting. We've got another bug to iron out, and I'll see about running it in a Linux Virtual Machine. Maybe then I can figure out what's going on.
Inevitably we're going to have to push a quick hot fix for the few minor issues others find, so hopefully we can figure this one out as well before the day is over.
Greetings HollowKnight after a longer period than is likely necessary, we actually found this is an issue with the ren'py as they've recently removed a specific function from the latest versions.
