BASE delete VARBINARY field from table

Hi. I created a table and added by error a VARBINARY field (I wanted a BOOLEAN). I’ve been trying to delee or edit the VARBINARY FIELD but I get an “Error while saving the table design” when saving the edited table.

Do I have to delete the entire table and start all over again?
