Idk if its only mine, but if i try to save, it says "failed to load". Im playing in browser version, and i understand that makes it more glitchy. If i try to press "retry", it just brings you back the that same screen.

I think I know what's the problem.
Did you have previous save files for the previous chapters? If the answer is yes, then it's highly possible that Chapter 4 recognized those save files and tried to load them which resulted in an error. Try getting rid of all save files (you might have to clear your cache/cookies though). I think this actually happened to me during chapter 2
