My Site URL is Blank On My Computer Only

Hello.

It all started a few days ago when I received a notification from wordfence that my core .js files had been modified across 5 of my sites. This led to several issues including not being ableto see things properly so I researched what I should do and I found that I should reinstall a clean version of wordpress. I did not do this correctly via the CPanel so I asked my host to restore it. After much chagrin they did, but now I can not access two of my sites at all (they show up as the url but blank white pages and I can’t log in to admin) AND the ones I can access, the visual editors are not showing anything.

Others say they can see them just fine on their end. I installed firefox to see if I could see the sites and I still can’t see them. This seems to be a local thing. What is happening and how do I fix this problem?
