I can connect to MariaDB with HeidiSQL and MySqlConnector, but when I try to view table data (all tables InnoDB) or make a query the MariaDB service crashes.
I get a popup: "SQL Error (2013): Lost connection to the MySQL server during query."
From the .err log
2023-01-12 17:33:30 3 [ERROR] [FATAL] InnoDB: Unknown error Failed, retry may succeed
