mariadb 11.0.2 crashed without error message

I am using MariaDB 11.0.2, upgraded from 10.5.x. some of the servers is good and working fast. the other one, is not. It start crashing after upgrade, but without an error message. when running as a service or when running directly in bash at root. $ mariadbd mariadbd: Please consult the Knowledge Base to find out how to run mysqld as root! 2023-07-04 0:42:07 0 [ERROR] Aborting What I tried: - reinstall MariaDB again - took server from backup, restore, and restart - restore a copy from working server via mariadb-backup - change the directory of data and start the server (work one time, but not the second one) where to start ? Debian 12, kernel 6.1.0-9 Thanks for all.
