“They were moving things off their phone and they canceled the transfer…” - that is the reason why SD card can become a RAW)))
Well, don’t worry, you can fix it with diskpart! That is in build windows tool. It is pretty much better than simple formatting!
You can use the algorithm from here SD card RAW format recovery (use the code from black&white picture).
But remember: that will remove all your files, so save them first. You can use their software - Uneraser or any other that you like, but restore files first - there will be a small chance to restore them after diskpart.
