Your examiners are not coming to your viva intending to crush your dreams. They don’t want to tear your work apart. They aren’t simply trying to find fault. They won’t give you corrections for the sake of it.
They might find mistakes, they might disagree, but they’re not there to ruin you. They’re not there to be mean.
Instead, they read, they look, they explore; they try to understand and ask questions to do so.
