While publishing my content in XD I accidentally closed that window. Tried opening and publishing the file again, but I am getting this error. I will lose old link of that published file if I create new link.
There is no solution at the link you referenced. There is only a mention of a badly written Adobe troubleshooting page that is not much help.
I also have this problem, and reconfiguring a complex file that is a fundamental resource which I shared with multiple external stakeholders is not an option. The problem is on Adobe's side as this is a core feature they have released that appears to be rather immature.
Please can you provide a real solution to this critical issue?
