iOS client crash, iphone x, self hosted server version 6.0.6

Hello,
the “seafile pro” ios client constantly crash on my iphone x.
The setup part is ok (I can see my libraries), but the app crash if I try to open a library (a popup briefly appears before the crash but I don’t have the time to read it)
Crash log here: https://filebin.net/mepuh7e83iyb5hh9
Thank you for your help!
