MariaDB error InnoDB: Upgrade after a crash is not supported

Here is a crash I experienced while upgrading MariaDB from 10.4 to 10.5

In previous versions Redo log was unnecessarily split into multiple files. Limited to 1 from MariaDB 10.5.

So in /var/lib/mysql/ I renamed ib_logfile0 and ib_logfile1 to ib_logfile0.old and ib_logfile1.old.
I restarted mariadb and upgraded my sql tables.

And it worked fine for me.
