I’m seeing the same issue across multiple users, and it’s happening with AutoCAD 2020 as well. This clearly looks like a Windows update problem. I hope Autodesk is already working with Microsoft, because the problem affects multiple versions of AutoCAD and it all started yesterday.
As of today, I’ve received 10 reports and the number is still growing. I’m an MSP who primarily supports architects, engineering firms, and interior design firms. This is a serious issue, and it needs Autodesk and Microsoft to be directly involved—not just us discussing it here.
