BUG: Can not generate ddl

[Naminee]

When I try to generate the ddl I'm getting the window to choose the path and a filename but the file won't be generated.
I tried it multiple times and also restarted the program but it just won't work.

Having the same issue

System Configuration

OS: MacOS Catalina
App version: 4.1.6

When I copy a table from the model to a new diagram and tried to generate DDL the file came with just 2 lines

SET FOREIGN_KEY_CHECKS = 0;
SET FOREIGN_KEY_CHECKS = 1;

When I added another table and tried to generate a new one, only the new table was added, like the copy-pasted tables never existed

SET FOREIGN_KEY_CHECKS = 0;
DROP TABLE IF EXISTS `hgh`;
SET FOREIGN_KEY_CHECKS = 1;

CREATE TABLE `hgh` (
    `ygjy` int(11) NOT NULL,
    `Column1` boolean(1) NOT NULL
);
