Path Exist Not Working

Hi! I am having an issue where the Path Exists activity is not following the loop–if the file doesn’t exist, then it keeps checking for it until it’s found. I watched the process and the folder where the file gets saved. The flowchart and decision just accepts the file exists; however, it wasn’t there. Because of this, the next action, Close Window, throws an error. I have an Assign Activity that makes the Exists variable False. For whatever reason, the Path Exists Activity is changing the value to True, even though the file does not yet exist. Any guidance would be greatly appreciated! Thank you in advance!
