I have the same problem with Mojave 10.14.6 on a new MacBook Air (used a MacBook Pro before and it worked fine) - tried to install and uninstall the app downloaded from Evernote.com and the AppStore, but nothing, it crashes after 4-5 seconds so I am unable to send the crash report to the Evernote team. I was instantly contacted be the support, but they don't seem to find a way to make it work.
