I have been using the same scripts in my Google sheets for several years, and today, when the sheet is copied, the onOpen function to create a custom menu does not appear.
If I try to run the function manually, I get a "Server Error" error message. Try to save the project again.
It seems that the problem affects all my sheets with user scripts when copying, the existing sheet function still works fine.
Has anyone experienced this in the last 6 hours? Perhaps this is just a Google server error?
