What can you tell us about the floor? Is it floating laminate/engineered? Is that glue I see in the gaps? How long has it been down?
Almost certainly you’ll have to start at one wall and remove the flooring up to the problem area and then re-lay it correctly. If it’s glued or nailed down it probably won’t come up unbroken, so you’ll be buying new flooring to lay down. And unless it’s a brand new install or you’re really lucky you won’t find that exact same product again so you’re replacing the whole floor.
