Nextcloud Notes crashes repetedly

[NoomiPetrinen]

This issue respects the following points:

• I have read the FAQ
• I have searched for existing issues
• The issue affects the Notes Android app, neither the Notes server app nor the Nextcloud Android app.

Describe the bug

Since a few days, Nextcloud Notes fails to synchronize and crashes. The pop-up saying 'Synchronisation failed' offers a 'more' button, but clicking on it closes the app.

Also, new notes are copies multiple times. These copies appear on tne nextcloud server backup and in the android nextcloud notes app.

Expected behavior

I cleared the cash and data, also freshly installed the app, restarted the phone several times. As the crashes keep happening, I assume its the app.
The rest of nextcloud works perfectly

4.5.0

[BraidenPsiuk]

Same issue on Google Pixel 6a with Android 16. Version 4.4.2 works well.

Can confirm that downgrading to 4.4.2 works as a temporary workaround.

Hello, thank you for the report.

Could you confirm whether you’re able to access and obtain the stack trace?

Hello,

Got the same issue, how i can get the logs ?

[cvigano]

I got the following from logcat when changing a note. Google Pixel 6a, Android 16. From the F-Droid version, tried removing and re-adding my Nextcloud account. Getting "Synchronization failed" and these error messages. I recently changed my web server from Apache to Caddy, but don't have any issues with other Nextcloud apps 🤔

This is the error I get when the app crashes after getting "Synchronization failed" and clicking on more:
