Always read studies for yourself instead of trusting headlines. In the study, researchers have looked for virus proteins in the nucleus of infected cells. We already know that the delayed and weak adaptive immune response is caused by the virus sending proteins into the nucleus of infected cells, where they suppress the gene expression needed to produce the stuff that alarms the immune system (and we know that ivermectin blocks the importer molecules used for that mechanism). The researchers have found more than one virus protein in the nucleus, including parts of the spike protein. Then they looked at DNA repair instead of gene expression, most likely because that's what they can do best. But DNA repair is quite uninteresting in a cell that is already doomed (either because it produces too many viruses or because a killer cell dissolves and mops the infected cell up).
