Thanks

That error code, 0xC00000FD, often points to a stack overflow issue in UiPath, which can happen if a workflow has too much recursion or too many variables. The recommended first step is usually to try restarting Studio, like the second error message says. If that doesn’t work, you might need to take a closer look at the workflow itself.
Restart studio first then check your workflow for any loop While or For Each running without a proper exit condition.
also try clearing the .local folder and reinstalling dependencies Manage Packages -repair If it still fails run Studio as Admin and update to the latest patch
Hello @hussain_shaikh,
Can you please remove all unrelated dependencies, variables, and also remove the cache and republish. This may resolve the issue.
Thanks,

Dim app As Microsoft.Office.Interop.Excel.Application
Try
app = CType(System.Runtime.InteropServices.Marshal.GetActiveObject(“Excel.Application”), Microsoft.Office.Interop.Excel.Application)
If app.Workbooks.Count = 0 Then
Throw New Exception("No Excel files are currently open.")
End If
Dim doc As Microsoft.Office.Interop.Excel.Workbook
doc = app.ActiveWorkbook
doc.Save()
System.Runtime.InteropServices.Marshal.ReleaseComObject(doc)
System.Runtime.InteropServices.Marshal.ReleaseComObject(app)
Catch ex As Exception
Throw New Exception("Error while saving Excel: " & ex.Message)
End Try
The error code 0xC00000FD indicates a Stack Overflow error. I would suggest first restarting UiPath Studio and then checking the workflow for any repeated or recursive workflow calls.
Also, try running a simple new project. If the simple project runs successfully, the issue may be related to the current project.
You can also check the Studio and Robot logs by clicking Open Logs. The detailed logs may show which workflow or activity is causing the Executor to crash.
If the issue still persists after restarting Studio, please share the detailed error from the logs so we can investigate further.
Hope this helps!
