I mean, no matter how careful you, or anyone else is, over time, you will get scratches on the lugs if you are changing straps.
That's a reality. The best thing to do is practice on a watch you don't care about so you can minimize your chances of scratching.
But it's going to happen.
As others have said, you could to see what could be done to fix it but it may be a bit of a challenge and may not be worth it.
This is just around 6 months of changing the strap (when required to remove spring bars) about a dozen or so times. And I consider myself to be decent at changing straps and quite careful while doing so....
I always go from the same side and this one is the worst one of the 2. I don't bother with taping.
And this picture makes it look even worse than it actually is.
