My chain was skipping gears under heavy load. I changed to another cassette and did a quick test, it looks like everything is alright. Could this wear on the cassette be the cause for the chain skipping gears?
PS: the chain is new.

It doesn’t look to bad did u check the chain as well to see if that needs to be changed
If a new chain skips on the cassette, the cassette is toast. (What about your chainrings?)
Since chains are cheaper than cassettes/chainrings, replace chain when worn as shown by a chain gauge to protect cassette + chainrings.
Probably the old chain and the old cassette were used to each other and on it together for a long time already. Replacing the chain can cause this behavior from your cassette if you waited too long with replacing.
So replacing both is probably the best thing you could have done!
Sounds like the chain and the cassette need to marry in and you need to adjust the derailleur for the cassette. I’d clean it all up and try again.
I don’t see any concerning traditional wear patterns, that cassette looks almost new. You should expect a little extra wear on the teeth specifically shaped to help shifting, since it’s thinner metal.
Do you know the make and model of the cassette? On brief lookup, it looks extremely close to a Shimano HG800 but with just a few details off. If it happens to be a knockoff cassette, then that would definitely explain skipping.
They are ussually toast before they look it. They definitely skip when they are done.
Not all, but at least two cogs are beyond worn.
