I am having the same issue. I can't type in search bar, the app appears to be infinitely syncing, I can't type or select anything or scroll. Super frustrating. I can't even click on the icon in my dock and have the app come forward. When I go to Evernote in Safari, search "works" but can't find anything. My Mac is running Mojave 10.14.5, and my app, which I have already uninstalled and reinstalled, is V7.10.
