What is normal for a cable-actuated clutch (for any brand) is that the cable will stretch over time and require replacement.
This is not your case here. 1- the bike is recent 2- the cable clearly is ripped out (not a case of normal wear)
Dealer should replace cable under warranty.
Possible cause is a bad quality cable where a few of the wires got detached from the hook that goes in the lever. With less wires in place and requiring the same force to pull the clutch, the poor remaining wires got stretched up to the point of having no more effect on pulling the clutch. If I see correctly, the wires still attached to the ball/hook appear longer (i.e stretched) than the ones that are "detached".
(Question: did the bike ever fell on the ground or something hit the lever ? We can see some paint chips on your lever and lever holder. If things got hit, it's not impossible it damaged some of the wires of the cables.)
