chain tension is too high, its binding
To quote Tuco Salamanca “tight, tight, tight.”
Chain is too tight. The runout from each rotating component causes the effective length of the chain to increase and decrease. You’ll notice as you rotate the cranks the tension on the chain will vary. It gets hard to turn because the chain tension increases. Once you pass the point of greatest eccentricity the chain tension eases and the crank will “spring” a little.
Give it some slack for the love of all that is holy. I like to give my chain about 1cm of slack on my fixed gear
This hurts the watch. Loosen the chain please
Loosen the chain and get something like this

Modular chain tension is a symptom of a loose chainring. Check the connection to the crank and, if present, the mating of the hat washer to the chain ring.
Like everyone said chain testing is too tight. You should set tension to the tightest spot not the loosest. Meaning if there is a loose spot in the chain how does the tight spot look? If you continue to tighten to the loosest spot then the tightest will be insanely tight. Hope that makes sense
Slacken that chain
Adjusting the chain tension on a single speed is always a little bit tricky. The fact that there isn’t anything to keep an even tension on the chain, the chain tension will slightly change throughout the rotation of the pedal. You always have to test the chain tension at more than one spot during the rotation of the pedal. It will go tight and then lose, and you want both to be acceptable. It looks to be too tight at that one spot but because you haven’t tested it at other spots I can’t tell for sure that it’s too tight, but it looks like it. Adjust the chain so it’s tight and when you rotate the pedal, it’s never loose enough that it will come off and you’ll be fine.
One of two things are happening, either the chain is too tight, or your free wheel is 5 times the age of the rest of the bike and needs lube added to it.
Too tight!
On an off topic note, did you buy this bike used or new? Nothing to do with the chain tension, just noticed it’s in a mint condition but the model came out like 3 years ago
