Cannot export a Datasmith scene to the Unreal Engine project root folder on MacOS.

This is mac specific. I could do the export normally on Windows with the same Twinmotion CL and UE version (5.5 preview). 
It is also a regression specific to 5.5, since I've been able to export a datasmith file to the same UE project with TM 2025.1 Main (Based on 5.4).

1 - Attempt to export the twinmotion scene as a datasmith file

2 - Select the destination as the root folder of your UE 5.5 project'

3 - Export

Result: The export is blocked. TM is asking you to set the export destination as  the root folder of your UE project.

Expected result: The export is initiated correctly, since you had the root folder selected in step 2
