Which general topic do you have

Hello,
I am currently facing a rather blocking issue on a Nextcloud instance and would like to know if other users have already encountered the same problem.
Issue description:
The following pages are completely blank / empty:
Administration β†’ Notifications
Personal settings β†’ Notifications
There is no visible error message, just no content displayed at all.
Context:
The Nextcloud instance works correctly otherwise (files, Talk, users, etc.)
SMTP is properly configured and tested (test email successfully received)
The issue seems to affect only the Notifications configuration UI
This prevents any configuration or verification of notifications (especially for Talk), both on the admin side and on the user side.
Questions:
Is this a known bug on certain Nextcloud versions?
Has anyone already experienced this behavior (blank Notifications pages)?
Is there a known fix or workaround (Notifications app re-enable, cache issue, specific version problem, etc.)?
Thank you in advance for your help and feedback.
