Sowohl 06 Plus - continue button

Hello, I recently bought a SV06 plus and it won’t print.
Every time I try to start a print I get the same error when starting.
It says to bring up the heat temperature for the nozzle and bed.
The nozzle reaches 195 Celsius and should be good to go.
now the screen advices me to press the continue button, which I press but still won’t start the printing process.

I tried the g.code bench file from the Website - didn’t work, all of my own files which I converted in Cura for Mac are also not working

does it have sth to do with the starting gcode ?

What’s about the bed ?
Could you check if the bed is correctly connected ?
