**Your software**  
My Mautic version is: 4.4.2  
My PHP version is: 8.0  
My Database type and version is: 10.3.29-MariaDB-0ubuntu0.20.04.1

**Your problem**  
My problem is: I can’t create new custom field for Boolean data type

These errors are showing in the log:  
[2022-12-01 19:02:04] mautic.WARNING: An exception occurred while executing ‘ALTER TABLE leads ADD ltv\_dc TINYINT(1) DEFAULT NULL’: SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘`databesname`.`paru`.`email`’ in ‘GENERATED ALWAYS’ {“hostname”:“MyPanel”,“pid”:677564}

Steps I have tried to fix the problem: don’t know what to do.
