Pretty sure your derailleur is on incorrectly. There’s a little tab on the black piece connecting the hanger and the derailleur – that tab should be behind the hanger.
Just loosen the bolt and rotate the whole thing backwards until it gets behind the mech hanger and it should be good.

RD is a Deore m5120 if it makes a difference

[your derailleur is incorrectly mounted, the B2 link should point backwards instead of down because its an adapter for attaching a direct mount derailleur to a conventional hanger, not a hanger extender](https://bettershifting.com/installation-guide/10-speed-and-11-speed-di2-road-rear-derailleur/)
