Sync fails with `DeadObjectException`

Describe the bug
opening the app shows 'Synchronisierung fehlgeschlagen' (sync failed). Notes cannot communicate until the phone is rebooted or the Nextcloud-app (NOT the notes-app!) is closed and reopened.

To Reproduce
Steps to reproduce the behavior:

• make sure Nextcloud-app is running in the background
• open Nextcloud Notes
  app is working as expected. After some time (regardless if the phone was in use or idle) the error occurs when opening 'notes'

Expected behavior
notes app keeps working

Screenshots

Smartphone (please complete the following information):

• Nextcloud Notes-Version (android app): 3.7.1
• F-Droid or Play Store: tried both, same problem
• Android-Version: 13 (LineageOS 20)
• Device: oneplus 9 pro

Problem occurs on this device only. Other devices with same apps/settings/account in the same network talking to the same server work fine all the time. Network is fine: nextcloud app itselfs keeps working, login with web-browser works fine while 'notes' shows the error
Are there particular settings/permissions required for 'notes' itselfs or the nextcloud app on oneplus (or A13)?

Server

• Nextcloud version: 25.0.3
• Nextcloud Notes version (server app): 4.6

Start with the stack trace in NotesServerSyncTask.java, especially pullRemoteChanges and run, then trace the Nextcloud Android SSO AIDL request that raises DeadObjectException. Reproduce on Android 13 with the listed app and server versions if possible; done means sync continues without requiring a reboot or restarting the Nextcloud app.
