You'll have to post a screenshot of your code.

If you're using a read call with an infinite timeout this would explain your problem (see here for other options).

that is a picture of the code i hope it helps

If the value of the timeout is -1 that would explain your problem (the DAQ Assistant will block indefinitely so the loop will never exit).

While it will not help with the stop issue in question, the stop button should be wired to the stop input of the DAQ Assistant and the stopped output to the loop terminal. This will allow the DAQ devices to be shut down properly.
