Error when creating/copying folder into vault

Dear All,
I am trying to synchronize data from local system drive into vault which is located in a OneDrive synch folder. Synchronization is using robocopy in a powershell script. It is working perfectly for the majority of the data, however, there are a few folders having trouble. Here is a sample output from robocopy log:

A device attached to the system is not functioning.

It´s a specific folder in my firefox profile. I already checked access right, there is no difference to others folders. Manual copy the folder also does not work with following screenshot:


This error happens for both dokany and webdav, mounted to virtual drive or custom folder. I am using Cryptomator 1.5.16 with dokany. Does anyone have any idea how I can solve this error? Thanks a lot.
