25 of May, Google released V51.x of Chrome
Episerver V7.x seams to work in edit,
But not V8.x or V9.x, gets a blank screen.
The same issue as in Epi ui crashes after latest Chrome update - the latest (9.6.2) EPiServer.CMS.UI nugets will fix it.
The fix is included in these packages
And they are now all available on nuget.episerver.com
