V2019.1.7 beta previewAuteur : Nigel P.
I to have this problem, I had upgraded to Beta 2019.1.7. This worked OK last week but now the preview is screwed ie it doesnt work. Uploading the site shows the details correctly via any browser.
I have tried the ctrl+preview suggested but no difference.
I re-downloaded 2019.1.6 and checked that and it now has the same problems.
I suspect a Windows 10 upgrade or patch.
