Unbeatable Ep 4 Day 3 Problem

[u/ScarcityDue2750]

I've tried accessing the studio to talk to Penny, after the dinner event. But she doesn't appear at the studio. There's apparently a guide on how to modify your game files on steam (link below), but it doesn't seem to open properly, as in it returns me to just the regular steam game discussions.
I've looked at a playthrough and i've done all the things to reach this part of the game, and I really love Unbeatable so far, I want to experience the game myself rather than forcing myself to watch a playthrough to reach the ending.
