I have the same setup as you and I have had the same issues since November last year. I initially contacted support who rebuilt the database structure for me, however, it can't be the issue because EN runs fine on my macbook (2016) and my new windows surface tablet.
IMO it's def a hardware incompatibility, but who knows how it's gonna be fixed. EN have had months to fix it and instead keep releasing updates which do not address the issue.
I've spent three days trying to find an alternative platform but I'm so invested into EN it's gonna be almost impossible. I'm spending over USD300 per year with these guys and I'm so frustrated.
