System.Windows.Forms.AllScreens works correctly in Debug mode but not in normal Run mode

Hello,

I’m working on a requirement in which the end users want the Automation to detect if the current machine is connected to multiple displays and if so, stop for user input before proceeding further.

Now, the issue is if the user clicks OK without switching to a single display, it results in an ambiguous situation. As a solution, the automation checks to see if the user has switched to a single screen by checking the System.Windows.Forms.AllScreens.Length and if the value returned is > 1 then the automation overrides the users choice of the OK button and stops running. Please see flow attached.

The problem:
This logic works as expected in Debug mode. However, if I run the process when in dual-display mode, and then switch to a single screen when the dialog prompt shows up, the automation is unable to detect the fact that I have a single display and stops the process! :neutral_face:

The User Action Dialog Prompt:

Works as expected when Flow is run in Debug mode with Breakpoint applied:

Results in Run Mode. This is incorrect, as I have switched to single screen mode:
