After updating Windows 10 to version 1809 there have been reports that AutoCAD can no longer be run. Affected AutoCAD versions are 2018 and 2019.
Upon start AutoCAD crashes with the following error message: “VLISP internal error”, “Unhandled exception on init”
To resolve the problem restore back to previous Windows version 1803.
It seems the 1809 update have been retracted for now. Should the update offer itself it is currently wise to postpone/decline.
