The first thing you need to do is verify whether this is an interference fit engine or not. If it is, then the intake valves in the cylinder head may be bent and the chain is irrelevant at this point.
You did not provide any details about this car (bought new or used, how regular the oil changes are, etc.) but it’s possible your timing chain was murdered rather than it dying a natural death of old age.
I think this engine uses an oil pressure operated tensioner with a tiny oil feed port. Runing the engine low on oil, low oil pressure due to a worn engine, oil sludging or coking cutting off feed oil to the tensioner, etc. could be behind this chain failure.
