Sounds like your callback function not really works. Callbacks/promises/async-await is used for asynchronous stuff when Innovator shall wait for another client task to be completed.
Regular code is executed synchronous. So it can happen that your Form is closing before something in between was finished. When using the debugger you slow down the whole process and you give Innovator more time for execution. -->That´s why your code works with debugger enabled.
I am not sure, but as far as I remember the AML Editor doesn´t use async calls at all?!? Classical Form callback looks something like this: community.aras.com/.../tech-tip-calling-a-date-dialog-from-a-method
Or you execute too much time consuming stuff inside the callback. This would require further callbacks :-).
