PlayStation Msb Introduction Unable To Complete

Hi all!
My first post here so be gentle
As the title says, I'm having trouble completing the introduction on the MSB.
It starts well. The train arrives and departs.
The troubles begin when you are told to switch to external camera and then back again to internal. After following the instructions, nothing more happens. The task bar is stuck at "return back to driver mode". I've tried everything, pushed every button to no avail. The train eventually arrives at Langenprozelten and never leaves.
Am I doing something wrong or is it a known issue?
I'm on a PS4 pro

Best regards.
