Email body simply not showing up

I have tried this many different ways but can’t figure out what’s wrong here.
I can not create any campaigns as an email template. It simply does not show up. I need to click on the Raw template icon, or the plain html template icon… all other icons simply just show a blank screen.
Have cleared all cookies, refreshed any CDNs etc… have tried two browsers. Nothing.
Please help.
