Same issue here. Downgraded to 3.12.4.
Problem:
Plugin not found, no installed plugin with that id
Fix:
in /etc/grafana/grafana.ini , Iine 728 [;allow_loading_unsigned_plugins =] delete ; and type [alexanderzobnin-zabbix-datasource]
like this [allow_loading_unsigned_plugins = alexanderzobnin-zabbix-datasource]
and restart daemon, you can see zabbix in datasource
