well, i maybe late but here it is anyways
you just need to go back to "NEW JOURNEY" and you will find the list of chapters
I played chapter 1 recently and I seem to be experiencing the same bug. I am opening new journey and then clicking on chapter 2, but it only makes a sound and doesn't do anything else. This applies to all the new chapters, only the first one is accessible to me.
I am using joiplay to play this game, so I might try to see if it works normal on my PC. I could also use save files of the nearest save location in those chapters, and just watch the beggining on yt.
*Update*
Yes it was a weird joiplay bug. The solution was to transfer the game to a PC, play a bit of the next chapter and save it anywhere.
