Right idea, wrong reason. You have a tonne of assumptions about how the product works that I don’t. If the bug is that subtle, dollars to Donuts says that one of your assumptions is wrong, but you just haven’t thought to question it yet.

When you explain the issue to me, I’ll ask dumb questions about context I lack, so you’ll explain stuff you take for granted. And it’s answering those questions that will make you figure out where the problem is.
