Page Builder doesn't load and keeps spinning tried on 5 different devices

Hi,

Suddenly I am not able to whether create new page or edit existing. The page builder is stuck on this (Screenshot below). The rest of Creator works, form builder, reports, workflows etc.

I tried opening the Page Editor on 5 different devices, including phone, iPad, then Safari on MacOS, Chrome on MacOS and Windows. It's all the same. 

Anyone any info?
