Saw this crash before, but I'm unsure if I changed some relevant code for that. You should update HeidiSQL anyway, v10.2 is outdated. Please install 10.3 at least, or even the latest build.

I just could reproduce that crash, by leaving no vertical space for the column definitions. So that after click on "Add column", the first column displays a non-visible editor. Like in your screenshot. I can probably find a fix for that.

Fix crash by click on "Add column" in table editor, when columns list has a minimum height. See
