Zabbix don't server doesn't start

Hello everyone,

Yesterday, I've done a Debian update, like I do once a month, if necessary.
After the reboot, Zabbix server doesn't start with the following error message :

May 17 14:41:05 zabbix systemd[1]: Stopped Zabbix Server.
May 17 14:41:05 zabbix systemd[1]: Starting Zabbix Server...
May 17 14:41:05 zabbix zabbix_server[896]: /usr/sbin/zabbix_server: symbol lookup error: /usr/sbin/zabbix_server: undefined symbol: usmHMAC192SHA256AuthProtocol
May 17 14:41:05 zabbix systemd[1]: zabbix-server.service: Control process exited, code=exited, status=127/n/a
May 17 14:41:05 zabbix systemd[1]: zabbix-server.service: Failed with result 'exit-code'.
May 17 14:41:05 zabbix systemd[1]: Failed to start Zabbix Server.

Nothing in /var/log/zabbix/zabbix_server.log

After a little search, I decided to restore a Veeam backup of the VM, wich I know the server started, same error.

I seems the error is not related to the Debian update, so I really don't know where to search.

Debian 11 and Zabbix 6.4.1 installed.

Do you have a clue ?

Thanks

Nicolas

Thanks for your reply.
I already checked on the forum and found this thread, but nothing works.

I saw the problem could be about SNMP, I had run those commands :

apt --reinstall install libsnmp*
apt --reinstall install snmp

Without success

I also change "localhost" by the internal IP of the server and reboot the server in /usr/share/zabbix/conf/zabbix.conf.php, same result, same error message.

Thanks !
