I replaced old chain for the same reason, currently had this chain for about 300km and it’s already like that.
What could be causing this?

Possibly a counterfeit or low quality chain? It’s also very dry.
Cheap counterfeit?
Is the simple green embrittlement thing still a thing?
I had this type of breakage happen with a new bike, and it was because my derailleur hangar was just ever slightly so loose. It broke my chain just like that one.
Failure to use a Regina de Ora 50 “Extra” chain with a matching Regina Oro Extra 6 speed freewheel. Of course, the must be mated Campagnolo Super Record derailleurs and shift levers–though Simplex LJ retrofriction work, too.

Guess: Chain is getting to tight and seeing crazy spikes in tension. Either single speed (or igh) adjusted too tight or multi speed in Big Big cross chain. Can you produce a picture in Big Big to evaluate?
Metal fatigue; simply replace link with quick link until you get a new chain.
Seeing a lot of this lately…
Cheap knock-off chain would be my guess.
What bike is it on?
