UPDATE failed because the following SET options have incorrect settings: ‘QUOTED_IDENTIFIER’

To avoid that error, I needed to add

SET ANSI_NULLS, QUOTED_IDENTIFIER ON;

for all my stored procs editing a table with a computed column.

You don’t need to add the SET inside the proc, just use it during creation, like this:

SET ANSI_NULLS, QUOTED_IDENTIFIER ON;
GO

CREATE PROCEDURE dbo.proc_myproc
...
