Description
### Problem Description
[Link IFC bug.zip](https://github.com/user-attachments/files/24862563/Link.IFC.bug.zip)
This Revit file exports fine to IFC.
It contains one single chair family.
The IFC file will open and display correctly on other IFC viewers such as BIM Vision.
But Revit is unable to link it back.
Link IFC only hangs and you have to terminate the Revit process.
### Revit Version
2025.4.x
### IFC for Revit Addon Version
25.4.40
### Windows Version
11 25H2
Contributor guide
Research direction
Download the attached Link.IFC.bug.zip and reproduce the hang by linking it in Revit 2025.4.x with IFC for Revit 25.4.40 on Windows 11. Compare the result with BIM Vision, then trace the Link IFC path for this single-chair export; done means Revit links the IFC without hanging or requiring process termination.
