Game works but graphics are bugged

[Prodigy]

I bought the game yesterday and installed it, then I completed Chapter 1 but other parts dont work, I already searched and checked the this graphic problem solution on internet but I couldnt find it.

Still chapter 1 works but when I try to play other 3 parts, there is same problem all graphics are totally messy. What should I do ? I have Nvidia 3060 series btw and already checked drivers.

Same here: I select any of the other episodes, it starts but nothing looks like normal. It's all a mess.

SOLVED:
Problem was that I purchased the Episodes 1-4 bundle from the store page. However somehow the purchase only counted for Episode 1. The invoice also only listed Episode 1 with its price but didn't mention the bundle with episodes 1-4. So I purchased the DLC Season Pass. Now the episodes are playable as intended. And it didn't count as a double purchase since as already mentioned above the Episode 1-4 bundle wasn't properly purchased but instead only episode 1. So even when the other episodes were selectable from the episodes menu they were not actually available or not really unlocked. Strange behaviour but anyway.

So > purchase the main game (Episode 1) and the Season Pass DLC.
