You can see it is happening on one particular link. A special type of link.

You need to investigate basic bicycle maintenance online. This is a great place to ask questions. Also do Google searches for videos on bike maintenance. As others have pointed out, your chain desperately needs lubrication. Your cassette has rust on it. You may want to remove it and clean the rust off.

1. Make sure the chain is well lubricated, as others have said.
2. Make sure the quick link is properly installed. Make sure to use a proper pair of chain pliers to close the link. This thing: https://www.decathlon.nl/p/missing-link-tang/_/R-p-363334
3. Check that every link moves (rotates) as it should. If any don’t, bend the chain sideways back and forth a bit around that link. Don’t go crazy, you just want to bend out enough to loosen up the link enough for it to be able to rotate.
I suspect (3) is the actual problem, but do the other two steps first just to make sure.

And in all that time it has never seen a thing called lubrication.
If you don’t look after your bike things will start to go wrong, For example a chain that previously worked can start to get stiff and inflexible because it needs lubrication to be able to move smoothly.

#1 – it’s happening at the quick link, it will probably be solved if you release and re-install the quick link properly.
#2 – oil your chain regularly
#3 – drivetrains don’t behave properly when you pedal backwards

Is that quick link the right size?

Chains need lube. Factory grease is actually perfectly okay lube, but it prioritizes corrosion protection over waterproofness or not attracting dirt. The link next to the quick link has gone stiff. You can usually break them free bending with your hands. Sometimes you have to give them a little sideways flex.
Right off the bat, I’d say that quick-link is misbehaving. Sometimes you get a funky one. Change it.

Make sure you degrease the chain before adding lube to it. Get some chain link pliers and on that link which is catching, drop it in an old pot/tub something that can get dirty and stay dirty add a bit of degreaser just enough to cover the chain and leave for a bit, add a bit of stirring motion, I even bought a 1-litre ultrasonic cleaner and run it in there for 5-10 minutes.
Once done, wait for it to dry, put it back in the bike and drip one drop of lube on every connection on the chain, leave for 30 minutes come back with a rag and wioe off the excess.
Definitely watch YouTube videos on removing a bike chain and adding lube

Grab it and bend it a bit from side to side to loosen it

Put each thumb on link next to bad link: push away hard: then with first finger behind same links, bend back towards you, repeat if necessary:: drop of lube on bad link before starting sometimes helps.

As mentioned before, you have a stiff link, next to your quick link. Grab firmly on both sides of the stiff link and flex it laterally back and forth 4-5 times, then see if it moves freely by hand. Rinse and repeat as necessary.
Get some lube and relube.

Looks like it needs some lube for starters.
Lubricate that chain, and dont backpedal.
Do you know about lubrication?
That quick link needs to be replaced.
