A way to upload an original UV layout to re-use on an object it was created for?

Hey guys, I’ve been working on a project and during sculpting/editing I’ve somehow managed to damage the original UV layout I had, which makes the texture I made for it have black spots/parts of the texture I don’t want on other parts of the object appearing, thankfully I have the original UV layout (the one i used to create the texture) saved on my computer, (the only thing wrong with the current uv layout is it has a slit down the middle, which wasn’t there on the original) Is there a way I can upload it into blender and re-apply this layout on the object?

(Pretty new to mesh creation)
