1035 error shuts down company

The 1035 error has shut down my company. I had lots of layout details, and if I try to copy my Google Sheet it breaks the layout. I have no idea how I can fix this error and I would be very thankful if somebody looked into this. I have been working on this app, FarmlyNC, for a couple years. It’s really advancing, but it’s stopped production!

Can you show us some screenshots of the error on your end?
