Hi Simon, thanks for your reply.
Yes, all the latest updates are installed for windows and autodesk.
I have had a closer look into this and can confirm that Autodesk do in fact use webview in at least some of their apps. The webview function based on Edge and/or Chromium has been integrated into the windows OS over the last few years and opened up to developers to utilise in their own software.
To my inexpert eye it seems it may be used to split the actions of the software into separate processes which can run simultaneously across multiple cores, reducing the load on the main thread/core which has to run sequentially. This may be more pertinent to autocad based products as opposed to revit which was developed separately. (I may be getting much of the terminology incorrect here)
This is my task manager which shows the various functions listed under Webview2

It is the very last entry containing the url seems to be the one that causes the issue for me, although here it is not causing a problem because I currently have internet access.
This page explains a little more about Webview, and links other resources about it.

I also found this autodesk support page relates to webview2 interfering with AutoCAD. Although the solution seems to be to install the latest version of Webview2 and I have already done so.

This is the link to the MS Dev page but I can't access it today (error 500)

This autodesk support article suggests as a last resort to uninstall and install webview2 from the original software package.

I've also tried to clip the text from the command line column but it's so long my software can't OCR the text.
