Automatic update of worksheet name in formula

Hi, Amy, I have a different problem, but I believe also related to the automatic update of worksheet name in formula: I decided to use lambda function to turn into formula a long command line, which had been working perfectly until then. The LAMBDA function also worked perfectly the first time. As soon as I closed the workbook and rebooted it, the function stopped working. I manually deleted the reference to the page at the beginning of the function and it returned to work. If you or others at the Tech Community can help with that too, I'd be very grateful.
