You can experiment with “SendWindowMessages” and “SimulateClick” in properties by setting one of them “True”.
Adding some delay using the “Delay Before” property can help too.
If you still cannot solve it, please upload a print screen of the whole “While loop” for context.
Do you absolutely need to use a Click activity?
It seems that the button you’re trying to press has a keyboard shortcut that can activate it, so you could use the Send Hotkey activity. This one does not require such a precise selector.
