Crash on Android 5.0

Hi, I like the idea of this App. However is crashes on my (rather old) Android Phone SAMSUNG Galaxy Alpha at start.
I use the f-droid version 1.6. It works on more recent phones (Android 9).

Sorry, I built it using Flutter, and I can't figure out what versions of Android it should work on. I tested on my phone, which has Android 9.
