Problems with database after upgrading debian12

How will this problem be solved?

Reading package list... Finished
E: The repository " bookworm Release" does not have a Release file.
N: It is not safe to update from this source, so it is disabled by default.
N: See the apt-secure(8) manual for details on repository creation and user configuration.

MariaDB has not yet publish packages

Disable bookworm Release in /etc/apt/sources.list.d and run apt update && apt upgrade

Does MariaDB not update on debian12 after disabling?

It will take it directly from Debian source instead of MariaDB server
