Cannot showing procedure after minor upgrade

Hi all, today i upgraded minor version from 10.1.21 to 10.1.31 (also 10.1.33) with step below

• stopping mariadb
• remove mariadb
• delete all datafiles
• delete configuration files
• install newest mariadb
• do mysql_upgrade
• do mysql_secure_installation
• join galera cluster

but after upgrade, i saw a weird error that either the procedure and function cannot be shown (see #error1).

It says "column length too big for column '(null)' (max = 65532); use BLOB or TEXT instead."

i thought that my db tool (toad for mysql) is error or something, but i tried upgrade toad for mysql to the newest version it still same. Also i try another db tool like dbeaver and heidisql are the same

i try to query directly by shell (see #error2) and facing same error.

i am sure every step i did was so true and nothing error happen, especially do mysql_upgrade.

FYI : i create new procedure then i run it, it was success but not for showing

*UPDATE : try to 'show procedure status' it went normal, but 'show function status' is not
