I am facing similar issue in “Type Into” activity in a web automation project. Current selector has been working well all this while and now fails sporadically (may work fine or may not if I try running the automation job in the next attempt)
Message: The UiElement is no longer valid
Source: Invoke - Customer Forms: Invoke- OpenCustomerForm: Type into 'INPUT - Email
Exception Type: InvalidUiElementException
UiPath.Core.InvalidUiElementException: The UiElement is no longer valid —> System.Runtime.InteropServices.COMException: Invalid UI node.
_ at UiPath.UiNodeClass.WriteText(String text, UiInputMethod inputMethod)_
_ at UiPath.Core.UiElement.WriteText(String text, InputMethod method)_
_ — End of inner exception stack trace —_
_ at UiPath.Core.Activities.InvokeWorkflowFile.EndExecute(AsyncCodeActivityContext context, IAsyncResult result)_

_ at System.Activities.AsyncCodeActivity.CompleteAsyncCodeActivityData.CompleteAsyncCodeActivityWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)_
Selector in use:
Upath version: 16.2.6274.33252.
Any help will be greatly appreciated.
