Inventor C# api to set Inventor.Property.Value crashes Inventor for Assembly files in Vault workspace

[Deepthi.Neeli]

We have custom addin in C# that does a SaveAs on an Inventor assembly file and sets some properties on the new file. This is crashing Inventor when Inventor is connected to a Vault workspace.
Version of Vault and Inventor we use are:
Vault server: 2023.3
Vault client: 2023.3

Inventor version: 2023.3

This code works fine in Default Inventor workspace(no Vault) and also on ipt files in a Vault workspace. But crashes on iam files in a Vault workspace.
Document doc = invApplication.ActiveDocument
doc.SaveAs(newFilePath, false);
PropertySet designTrackingProperties = doc.PropertySets["Design Tracking Properties"];
Property propNumber = designTrackingProperties.get_ItemByPropId((int)PropertiesForDesignTrackingPropertiesEnum.kPartNumberDesignTrackingProperties);
propNumber .Value = "Test-PartNumber";

I think this is a bug.  I tried a SaveAs (SaveCopyAs=false) on an assembly I had checked out from Vault.  The new assembly show checked out to me AND checked out to the old assembly (not a user!).  If I do the same on a checked-in file, it shows up as "Unknown status".  I think the workaround would be to SaveCopyAs=true and open the file to modify its iProperties.
