Selector looks fine but does not attach window

Hi there,

When I run or debug my workflow it could not attach the window and gives timeout exception. When I select the window manually it continues to workflow without problem. I checked and tried several valid selectors for attach window activity. Do you have any offers to try?
The application is desktop .net windows forms application


Installer(.exe or .msi): .exe

License type(Free, Trial/License code): Free Community

Studio/Robot version: 19.5


use that Activity inside Attach Window Activity and then try again.

Already İ am using activities inside attach window
