It’s a rockrider which my kid rides
Whenever she shifts to the largest cog it gets stuck there.
You can see that the derailleur is almost touching the sprocket which I presume is causing the issue.
When I push the derailleur inside and shift back it goes to the next sprocket again.
I have no clue how to set this up properly.
Any ideas what must be done?

Also… yes I will clean and lube the chain once it’s fixed.
Adjust the b screw to move the upper jockey wheel further away from the biggest cog.
Look up “B screw derailleur” on YouTube.
Featured snippet from the web:
The B-screw is used to set the gap between the derailleur guide pulley and the largest cassette sprocket. You’ll want this gap to be relatively small, without having the guide pulley touch the sprocket cogs.
