Crash of 4.2.1

Rocket.Chat Version: 2.3.1 via Snap |
NodeJS Version: 8.15.1 - x64 |
MongoDB Version: 3.6.14 |
MongoDB Engine: wiredTiger

I just installed the RocketChat App 4.2.1 on my iPhone 8. It updated flawless from 4.1.0 to my account. I gave a emoticon-feedback on a posting, and the trouble begun:

• the Comment didn't show up
• In the overview page it read "no comment"
• The App crashed a few seconds after.
• Every attempt to restart the App: immediate crash to Springboard.
• I deletet the app an logged in again: same behaviour.
• I deleted the app an logged in with a different account: success!! O__o
• On every other device the first account still works.

What went wrong, and how can I "repair" my first account (I'm admin on my own server, running a Snap install).
