This has kind of been the expectation of JWST and why it was so anticipated and is so exciting. The whole point is to collect new data that challenges our understanding and learn new things.

These articles are usually written in a highly sensationalized way. Our understanding of what "should be possible" is based on computer models/simulations. These new, hard to explain observations have taught us that our models were not detailed or precise enough, or need to have parameters adjusted to accurately reproduce them, without needing to break our theories of the big bang and an expanding universe. We don't even need to throw out the old models, because they are still useful and great for modeling most of the universe, just understand that there are limitations for using them to model the very early universe

There are definitely big mysteries yet to be explained and a lot to learn and figure out. The Hubble Tension comes to mind, and that one does make me a bit suspicious that something isn't quite right.
