After I connect my Kobo Aura I get an errormessage "error communicating with device". I can upload ebooks to my device though. Everything seems to be normal. However yesterday I noticed that almost all collections on my device had disappeared.
This communicating problem is recent, in any case after the upgrade to the 1.34 version of Calibre. I appreciate your help.

The error log:

calibre, version 1.34.0
ERROR: Error: Error communicating with device

database or disk is full
