To learn sp_executesql, I create a small code. It works fine as below.

CREATE TABLE [dbo].[#A](
        [authno] [nchar](10) NULL,
        [Authname] [nvarchar](50) NULL
) ON [PRIMARY]

INSERT INTO #A (AUTHNO, AUTHNAME)
VALUES('444' + '~', 'EEE')

Once run sp_executesq, got an error said

Incorrect syntax near '444'. How to fix it?

CREATE TABLE [dbo].[#A](
        [authno] [nchar](10) NULL,
        [Authname] [nvarchar](50) NULL
) ON [PRIMARY]

DECLARE @sql nvarchar(200)
set @sql = N'
INSERT INTO #A (AUTHNO, AUTHNAME)
VALUES('444' + '~', 'EEE')'
exec sp_executesql @sql

How about this

DECLARE @sql nvarchar(200)
set @sql = N'
INSERT INTO #A (AUTHNO, AUTHNAME)
VALUES(''444'' + ''~'', ''EEE'')'
exec sp_executesql @sql

Dynamic SQL is an advanced feature, and if you feel obliged to ask this
question, you should probably defer working with dynamic SQL, until you
master the basics better.

That said, I have an article on my web site, which covers dynamic SQL
in depth: http://www.sommarskog.se/dynamic_sql.html.

To expand on this, when you need a quote in a string it has to be escaped
with another single quote.
