Kind of strange error with network location of dynamo files

Hi everybody,

could not find a similar case yet. This started from Dynamo 1.1.0 (+Revit 2016) on.
When opening Dynamo files from a network location that physically currently is not available but that was synchronised with Windows Sync Center I get an "Unknown Error while opening…"
However, saving Dynamo files to that “network” location is available.

Here’s the details of the notification:
System.InvalidOperationException: Unerwarteter Methodenfehler 50.

Thanks for reading.

Hi @MarHof3835

Do you have read and write access to your network folder/files?

Yes I have.
I can create files and folders within them, I tried several different paths and even provided folder and file names without blanks.
Every other software tool reads and writes files to and from there with no problems.

I verified that there seems to be an issue with Windows Sync-ed files.
When the network location is available and connected, Dynamo opens the very same files without any problem. So my guess was correct?!
