Anyone know why I am getting this error from my Archicad Datasmith?

It's happening for both my ArchiCad25 and ArchiCad 26 installations, with any version of Twinmotion. Mac OS Monterey on an M1 Max

Unable to create/access assets cache folder: "/var/folders/q5/gqcwy5hj49s98c_c_lzpw0qm0000gn/T/DLExporter"* Caught an exception "Error "Unknown value -2130640381" at "/Users/build/Build/++UE5/Sync/Engine/Source/Programs/Enterprise/Datasmith/DatasmithARCHICADExporter/Private/TexturesCache.cpp:345"" in FPaletteWindow - ButtonClicked

Hi ,

Thanks! Is there a typical folder location or somewhere in the system where the cache folder should go?

It is usually inside the UE5 folder '...\UE_5.0\Engine\Source\Programs\Enterprise/Datasmith/DatasmithARCHICADExporter/Private/'

It could be that the path no longer exists after updating Datasmith, Engine or Twinmotion. Then the error occurs.

Cheers,
