Star process activity issue

st Hi Team,

I am unable to open “.xlsm” file using start process activity,
I was using this activity from last 1 year and suddenly stopped working from today.
Throwing error as

"System.Exception: Application could not be opened
at UiPath.Core.Activities.TaskAsyncCodeActivity`1.EndExecute(AsyncCodeActivityContext context, IAsyncResult result)
at System.Activities.AsyncCodeActivity.System.Activities.IAsyncCodeActivity.FinishExecution(AsyncCodeActivityContext context, IAsyncResult result)
at System.Activities.AsyncCodeActivity.CompleteAsyncCodeActivityData.CompleteAsyncCodeActivityWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)


Check below

Hope this helps you
