Got this upon closing Excel:

The text in the details:

The underlying reason seems to be a disconnected COM RCW Wrapper:

System.Runtime.InteropServices.InvalidComObjectException: COM object that has been separated from its underlying RCW cannot be used.

We currently only have an issue pertaining to powerpoint open with this error: #4757

This has been introduced with the PR bringing the reference nodes to the CE. The problem is that it is still trying to get the reference information from the VBE when we are already in the shutdown.

I would say the source of the problem comes from this:

https://github.com/rubberduck-vba/Rubberduck/blob/4e1844a568445a9ef6675aa96c2401b231bf9031/Rubberduck.Core/Navigation/CodeExplorer/CodeExplorerViewModel.cs#L217-L245

We start to turn off the event pipeline via this:

https://github.com/rubberduck-vba/Rubberduck/blob/5af7fed2dc4eadf7d5f2867287b22efda0020b3a/Rubberduck.Main/Extension.cs#L257

into:

https://github.com/rubberduck-vba/Rubberduck/blob/5af7fed2dc4eadf7d5f2867287b22efda0020b3a/Rubberduck.VBEEditor/Events/VBENativeServices.cs#L41-L54

The problem, though is that the RPS does not currently listen to the Terminate event:

https://github.com/rubberduck-vba/Rubberduck/blob/5af7fed2dc4eadf7d5f2867287b22efda0020b3a/Rubberduck.Parsing/VBA/RubberduckParserState.cs#L203-L211

It probably needs to start listening to it and use it to cancel the current parse & stop broadcasting its own events.

Not sure if this is related or not, but I'll post as additional info:

Had an XLSM open with the VBE open and the project parsed (.4533).
Opened an XLSX
RD parsed (the VBE was in the background)
Got the JIT debugging info.

Have just had the same or similar, twice on successive RubberDuck refreshes. Excel had been open for an hour or two doing desultory editing of code and code-behind-form modules, running code to test.
After clicking Continue on the .NET dialog, refreshing seemed to complete normally. Restarting Excel appears to have made the problem go away.

Same again, though Excel had been open, mostly idle, for much longer. Please let me know if there's anything more helpful I can do next time.
