Thank you for sharing the logs, @stolzyhe01! Here is the error.

Do you get an error about PowerShell being blocked when you open Revit? Here is an installer that addresses that specific issue.

Also, are you able to save as the file as a DFJSON instead of trying to save as PoMF? That way we can recover your current work after updating the installation.
