Oh yes... The infamous "Insane Objects"... They can drive you insane... 😮 😉
Basically, (for some reason), somethings gets corrupted in the vi block diagram. Until recently, the solution was to simple copy & paste into a new blank diagram. I recently read that there is a way to actually trap (see?) what the actual object is.. I'll try to find the thread which discusses it.
Here are some links for your reading pleasure:
Have a look at the 4th post in this thread:

Hope this helps,
Did you try the infamous "select all / copy / open new blank vi / paste / save as original_filename" approach?
I am really curious about what led you to believe that an Intensity Chart is causing the errors. Are you able to save the VI without the insane object, then add an intensity chart and get the error? Maybe you could share your VI with us so we can see the insane object.
I must admit, this is the first time that I read that the entire Front Panel became an insane object.
