Problem with writing files to mapped disc

Hi,
the problem is with writing files to a mapped drive Dropbox or Onedrive. I’m getting failures when I open file
and want to close/write to the disk. NetDrive send me some information about failure (screenshot) and I can
not do anything with this file and also with NetDrive, I can not close/disconect etc. Help only restart of system !!!

Can me help install older version?

NetDrive version: 3.6.319
Mac Version: High Sierra 10.13.6

Dear milos.krasnicky.

Could you attach debug log files to figure out what happened?

After setting the log level to VERBOSE, please reproduce the problem and send us the debug log file :
