error: "import est. time remaining 1 min" with premade layouts

Hi there - I'm trying to use some of the premade layouts in Divi, but it is just getting stuck with a never ending loading bar.. "Import estimated time remaining 1 min".

I've searched around and other people have had this error when uploading their own layouts, but I'm trying to use the "restaurant" or other layouts that are already uploaded as standard with Divi.

Has anyone else had this problem?

Thanks!
Tas
