After “pinching” on of the component on the back of the Nebula bord (screen), I managed to get like 10 minutes of working touch screen. This allowed me to configure WiFi and setup connection to Cloud at least.
Component : What electronic component is this on Nebula board?
I don’t know if this is related or just make another bad contact working again by disassembling it. The problem will be solved soon since Creality support would replace the screen.
