I think they call this the appeal to authority fallacy, it’s the people without expertise in a field that often see the holes in something first, then the holes start glowing after they get hand waved away by smug narrow-minded experts.

While it's obvious that everybody makes mistakes and has blind spots, I'd wager that, in general, being more knowledgeable gives you better tools to spot actual holes.

And sure, experts too can be narrow-minded and smug. Just like everybody else.

Being an expert always adds a big weakness: You get paid to do this so you are biased.

So no, they are not "just like everybody else", they have spent more time on it so they know some things better, but you can't get away from biases that comes from being paid to do something and that makes experts worse at some other things.

No they don't. That never happens. Would you expect someone who knows nothing about programming to identify flaws in a computer language?

Of course not. You expect it will be people who actually understand the field that can identify issues.

it can even happen in software engineering but takes different forms, someone outside sees the problem first because they are looking from a different perspective or due to familiarity with some external factor or edge case of their environment

Example?

and what are you engaged in, appeal to nothingness? appeal to authority isn't a fallacy outside of formal logic, it is just everyday knowledgemaking.

Everyday knowledgemaking is filled with fallacies.

And we make myriad daily mistakes because of them. Most have no real negative consequences, so we don't correct.
