Hi

It looks that you have an old version of Mysql/MariaDB because JSON_ARRAYAGG is missing.

JSON_ARRAYAGG was added in MySQL version 5.7.22 and in MariaDB version 10.5.0

You need to upgrade your database or reinstall using SQLite instead of MySql.

You can delete config/db.php to reset db config and install page will show to choose SQLite.
