Backup was taken on 10.3.17 MariaDB - copied /var/lib/mysql directory
Restored on 10.2.22 MAriaDB - pasted the backed up directory contents.

Restarted mariadb db service using the below command,
systemctl restart mariadb

This method of backup/restore of mariadb databases worked in our product. But in this particular scenario we see that once the mariadb service is restarted, the table updates fail. Below are the logs & other information.

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
