Altus on windows doesn't load chats since android update including gemini

[RenoMuc]

Hello,

since my smartphone Samsung Galaxy SM-A145P/DS has been updated to One UI-Version 7.0 (Android 15), the Altus App on Windows doesn't load any chat but shows only "Load WhatsApp for Windows"

I disconnected and reconnected the devices several times with no success.

I deactivated Gemini without any effect on Altus. Deinstallation of Gemini is not possible.

Any help is appreciated, because I use Altus daily multiple times

Best regards
Reno
