The report from user:

I'm running MariaDB 11.6.2 on Ubuntu 24.04. Within /etc/mysql/mariadb.conf.d/50-server.cnf I enabled the parsec plugin as described in the mariadb docs via plugin_load_add = auth_parsec.

MariaDB emmits these ERRORs on startup:

Nov 21 19:34:03 XXX mariadbd[46425]: 2024-11-21 19:34:03 0 [ERROR] Couldn't load plugins from 'auth_parsec.so'.

Adding plugin_maturity = beta to the conf solved the issue for now. I guess the Plugin maturity hasn't been bumped when going from 11.6.1 to 11.6.2.
