Illustrator error occurred: 1129270854 ('FNOC')

I’ve been using a script to make our Proofs Smaller and locked w password to be able to send through email and since updating illustrator it gives this code now. 1129270854 ('FNOC') It worked in illustrator 2024 and not 2026. Im not really techy to figure it out. I saw a few post saying something about open art boards but I’m usually only using one art board.
