Measured 117mm on 9 chain links which means 2.3mm larger than new or 2.36% wear.
Do I need to repalce chainring too or just the chain?

Just keep riding it till you get to 5% and then replace it all
you may have a 1/8 chain on a 3/32 chain ring.
Replace the entire drive train. Too much wear on “the big cookie.” Rear cassette probably equally worn out. No surprise the chain is jumping off.
You need a new chain ring replace the chain at the same time check your cassette if the teeth come to Sharp points like that on the chainring you’ll need a new cassette also. The chain obviously has nothing to grab onto I’m surprised it’s not jumping when you pedal the bike.
You’re either showing a 3/32″ chain on a 1/8″ chainring or a very stretched chain on a *good* chainring, as the chain is riding (very) high, which happens when the chain pitch is longer than the ring pitch, such as when the chain is very stretched. Or you’re showing some other error I can’t see that’s causing the chain to ride high.
From your measurements, the chain is a bit stretched. The chainring, though, looks REALLY worn. I’d replace them both.
