unable to open account settings

Using 64-bit Linux Mint 19.1 MATE (based on Ubuntu 18.04) and Jami built on 2019-06-29 05:14:54 UTC. When opening Settings then Account part is not opening. Also cannot see the PIN needed to log in at smartphone (Android). Also cannot export settings. When trying to open then nothing happens. If any other choice is active then clicking on Account does show that previous one but not Account part.
