I was riding and noticed my chain skipping, upon closer inspection I saw this. Anyone have a clue what could have led to this, and/or how to fix this? I was thinking of putting a second quick link in its place.

Fake chain maybe? Bought off Amazon?
I would replace it and focus on regular maintenance with the new one.
Looks like your chain is pretty dirty. Lubing and cleaning your chain will make it lifespan increase drastically. Depending on what conditions your riding in you should get a wet or a dry lube. I personally use rock and roll dry lube it cleans and waxes your chain to keep dust and dirt off of it. But I have no experience with wet lube.
Error with manufacturing or a very unlikely rock strike is all I can think of.
throwing down too many watts for too many miles 😉 how’s your legs?
I’m not sure if it’s a contributing factor, but CN-6701 is a directional chain and those slots are supposed to be facing in towards the bike. Having it this way is likely to have led to slightly poorer shifting.
I wouldn’t even put much thought into this and would have replaced it by now.
Switch to wet lube or try gear oil. Best thing I did for my chains.
You may have put too much power when shifting a gear? (to a higher gear at the rear I guess) and too much force&tension through the chain + lateral force during the shift = this?
(my guess though, but seems possible)
Was it really stretched?
It looks like this particular link was rubbing for some reason. The wear looks pretty obvious, doesn’t it?
What bike?
Bike mechanic here with over 20 years of experience. I suggest checking the chain to see how stretched it is if it’s less than 75% stretched I would just get a quick link and replace that link that is broken. I also would suggest soaking/cleaning your chain thoroughly and lubing it properly….best of luck to you
Quick links are a sort term keep you riding fix for me. I’d replace the chain at the next opportunity.
Also, and please understand I trying to be helpful not critical – you don’t shift gears while pedalling hard or climbing do you?
Go completely down the rabbit hole at zerofrictioncycling.
Is it a quality made in Japan chain or an Aliexpress spécial…. was it properly adjusted and are your sprockets worn out.
If you happen to shift while climbing or under load often it can weaken the plate and crack as it is with yours. There also seems to be more wear on that link than the ones near it. Perhaps due to weird odds that link happened to be at the shifting point more often than the rest leading to failure.
