Just in case anyone is still running Thunderbird 52 for compatibility with legacy addons and is wondering why tbsync has forgotten your NextCloud CalDAV / CardDAV account information and stops responding when you try to add a new CalDAV or CardDAV account: The problem isn't tbsync, it's Provider for CalDAV & CardDAV. As of version 0.11, Provider for CalDAV & CardDAV is now broken in Thunderbird 52, Rolling back to version 0.10 solves the problem.

이 검토는 현재 부가 기능의 이전 (1.1) 버전에 대한 것입니다. 

Thanks for catching this. I updated the min version setting to TB60.
