You need to rip the carpet out somehow from the bits with the spikes then lever up the metal strip with a crowbar and replace it with the wide strip that covers the damaged carpet edges. Some of them have two parts and the upper part is pushed into a groove in the lower part but if a bit of levering doesn't do anything you can conclude it's all one piece

The carpet edges are already out so they can't have been very well
gripped in the first place. Levering is about to begin.
