I am also experiencing this issue with Mautic 4.2.2

Here’s my error when trying to create a select-multiple custom field:

```auto
 An exception occurred while executing 'ALTER TABLE leads ADD vol_type VARCHAR(255) DEFAULT NULL': SQLSTATE[42S22]: Column not found: 1054 Unknown column '`XXXXX`.`l`.`email`' in 'GENERATED ALWAYS' 

```
