We Exploded the AMD Ryzen 7 7800X3D and Melted the Motherboard

Unfortunately there is always a risk of ending up with defective components. In same ways this is a better outcome than getting a random defective chip, because the manufacturer/vendor cannot make the claim of user error as easily.

For what it's worth, these kind of manufacturer errors are very rare these days. Most PCs people build just work right away. And everyone involved is almost certain to get their full money back.

You could probably go with an AM4 board and a 5800x3d instead. Pretty close performance, a lot lower price, not many complaints about lack of magic smoke retention.

Sure, you lose out on future proofing, with no pci-e 5 and no ddr-5, but eh. Might be better to get into something at the end of the platform, rather than the beginning of a platform. Or you can stay on the wait and see train and maybe next year's systems will be a better choice. AM4 had issues for the first round or two, and Zen3 was pretty nice; it's a pattern that repeats (which is probably why AMD keeps sockets longer, Intel shows this sometimes too, but it's not so pronounced)
