Family is corrupt and cannot be edited in Revit 2020.2

Issue:

Users reported that when working in a Revit 2020 project, they encounter the following message:
"Family < family name> is corrupt and cannot be edited. Please reload the family to repair the project."

Environment:

Revit 2020.2

Status:

This incident is being investigated for a possible cause and resolution.

Additional Information:

This issue is specific to projects which were created in Revit 2020, and later worked on in Revit 2020.2

Workaround:

If not currently working in the Revit 2020.2 version, avoid updating until a fix for this has been released

If currently working in the Revit 2020.2 version, there are a few one-time operations you can take in a Revit 2020.2 build to prevent the issue:

• Rename all families in the project (e.g. FamilyX to FamilyX-2 and then back to FamilyX) OR
• Save the model as a new central (must be a new file, not Save As to the same location) OR
• Reload all families (including company, Autodesk, and 3rd party families) in the project OR
• Move the entire project team back to Revit 2020.1

If the team is working on mixed versions, we suggest first getting everyone onto the same version. Working in a mix of Revit 2020.2 and earlier versions can reintroduce the issue to model(s).
