Question Error while loading a project via Reflect Window

Hello,

In the Editor, Unity 2020.2.1f1, I installed the Unity Reflect 2.1.0-preview.106 package.
Then I try to download a model that was exported via the Revit 2023 plugin.

During the download I get everytime a message of the sort : "System.AggregateException: One or more errors occurred. ---> System.IO.FileNotFoundException: Could not find file "D:\02.UnityProjects\ReflectImporter\Assets\Reflect\Cache\A\A.rvt_IFC_export 3D_04BBB917\.download\instances\BB_05.06_Isolatie_Dakrand 60 x 420 [12519030].SyncInstance"

Now, it's not like there's nothing in that .download\instances\ folder, there are lots of other SyncInstances, but indeed not that one..
I initially thought it might be due to a too long path, but tried to shorten it, and it didn't help.
Also tried on another PC, same error.

Does anyone have an idea why this might happen?

I know I'm supposed to clone the git repo, but for my present case I just need to import the model and use the package instead.

Thanks a lot,
Arnaud

 

Did you manage to solve it? I'm having the same problem here.
