Issue
When you try to preview a Flow from a Task List, the Task List flickers or opens and closes unexpectedly.
Probable Causes
Studio is unable to detect the correct UI element to launch the Flow. As a result, the Task List might behave incorrectly.
The configured CSS Selectors don't point to the correct element or are unable to identify the element.
One or more CSS Selectors are invalid. For example, the class or id of an element is incorrectly copied. For more information, see Selected Element conditions as Visibility Rules.
Suggested Solutions
Reselect the element and verify if the CSS Selectors are configured correctly. For more information, see How to find the CSS Selector of an element?
Verify if the starting URL of the Flow is correct. For more information, see Change the source URL of a Flow.
