On an iMac built in 2019 running MacOS 10.15.3 Catalina I did a fresh install of Enpass 6.4
After connecting Enpass to the data on "my" iCloud and then having a successful synchronization, now I am unable to do anything with the Enpass software except exiting it.
All the rest of my devices (iPhone / iPad / MacBook Pro) work fine with the newest Version of Enpass and my iCloud data. What can I do next to solve this problem?
