Activating Plugin results in “Page… unable to handle this request”

Once I have this plugin installed and choose to “Activate” it, I get a HTTP Error 500: “This page isn’t working. <address> is currently unable to handle this request.” I then have to back it out by deleting the plugin directory from my WP installation.

I use this plugin on different sites without issue (though they have been installed for some time), so I’m wondering if this might be highlighting a potential conflict somewhere?

For troubleshooting’s sake, I deactivated all of my other plugins, but got the same behavior. Here is the current environment:

WP Version: 4.8.1
Easy Google Fonts Version: 1.4.3
WP Theme: MaxBusiness
