Customize Form reach the maximum column! what should i do?

i think i reached the maximum column the system can reach(134rows)
what can i do to add more rows or delete those i don’t need but is built in the system?

This is a MariaDB limitation. MariaDB tables can only have a maximum row size of 65,535 bytes.

To work around this, change some of your custom field types from “data” (or whatever it is) to “Text” - this means it is stored as a blob in MariaDB.

The following is some good reading on the subject:
