Uipath studio project debug mode vs run mode


I am facing a problem with the execution mode in uipath studio. I built a project in uipath studio and when I run it using debug mode everything works fine. but when I try with the run mode it doesn’t work! it does not recognize the selector that I put in the activity “on Element Appear” and raises the error “Activity timeout execeeded”

This is what the part where the error is declared looks like:

Here is what my selector looks like:

Can someone help me?

Thank you
