Android app crashes on local sync attempt

I have the same problem since a few days. Here what I have done so far:

Phone: App version 1.7-7, Android 10

Server Ubuntu 22.04 fully updated, Everdo 1.8.5 (PRO)

Sync over LAN

Was working fine for a year. No updates of app on the phone or PC recently

Desktop app works fine, doesn’t crash.

Android app works fine when wifi is disabled, in the moment wifi is available and it tried to sync it crashed. Crash report sent. Log file sometimes available (see screenshot)

I reinstalled the app, did a clean pull – same crashing

Did a reinstall and an import json. Got an error message (see screenshot)
I do not know how to get the logfile for Everdo desktop app.
