I fix the machines that fight climate change
Your gear hanger will have been a bit bent. Happens all the time. They're meant to bend easily as they're replaceable and it saves the frame being a write-off when the bike's fallen over to the right/been shoved by someone else putting their bike in beside it in a bike rack etc etc. But if you don't notice it in time the mech gets caught in the spokes when you're in an easier gear as has happened here. It's not going to be cheap to fix though I'm afraid it'll usually be a new rear mech, new gear hanger, replace any badly cut spokes in the wheel, new chain if it's twisted and maybe cassette on the rear wheel too if the chain was worn. Sorry.
