Before proceeding, make sure to take a backup of your database and the affected tables, or work on a staging/development environment to avoid any potential data loss.

SELECT * FROM salesrule WHERE your_serialized_field LIKE '%s: %';

Replace your_serialized_field with the specific column that contains the serialized data.

Remove Invalid Entries.
