In its Abstract it says:
We highlight the application of CRISPR technology as an emerging pan-antiviral therapy. We also discuss the challenges of in vivo delivery of CRISPR components and propose novel approaches to achieve selective delivery exclusively into SARS-CoV-2-infected cells with high efficiency by hijacking the surface proteins of SARS-CoV-2.

What that means is that we would take the long detour of editing our genes first, that would then trigger the autoimmune system to develop resistance to the modified genes that look like the COVID19 virus via CRISPR, to fight off the invading viruses.
This very circuitous way of dealing with the problem, hoax or not, is a common feature of a scam, because no individual outside of the medical priesthood can verify how effective would it be, or that its results can only be verified using their own diagnostic infrastructure, which means that they can claim whatever they want, even when contrary to empirical evidence.
In the meantime, directly electrocuting all types of viruses in the bloodstream is already being done by thousands of individuals using the device described at the homepage of this website.
Anyway, to circumvent their post-publication censorship, a snapshot of the NIH article is saved here.
