LabVIEW Crash with Unknown Exception When Trying to Edit Timed Loop

Issue Details

I have a VI with a timed loop that causes a LabVIEW crash everytime I try to edit this loop. I receive the following message:
Additionally everytime I try to save the VI I also get a crash. 


This behavior can be fixed by deleting the timed loop and replacing it with a new one. 

Additional Information

  • This type of crashes can happen not only with timed loops but also with other LabVIEW functions and structures. The solution in general would be to delete the element causing the crash and replace it with a new one. 
  • This behavior could indicate that the code associated with that particular function or structure is corrupt.
