Possible Solution : Insert data to backup table in chunk.

DECLARE @rerord_count INT = 1;
WHILE @rerord_count > 0
BEGIN
  BEGIN TRANSACTION;
  INSERT USER_TABLE_2023_BKP19JULY2023(USERNAME, PROGRAM,USER_STATUS)
    SELECT TOP (5000)  USERNAME, PROGRAM,USER_STATUS 
    FROM USER_TABLE_2023 AS ST
    WHERE NOT EXISTS 
    (
      SELECT 1 FROM USER_TABLE_2023_BKP19JULY2023 AS TT
      WHERE cast(TT.USERNAME as VARCHAR(100))+'#$----$#'

            +cast(TT.PROGRAM as VARCHAR(100))+'#$----$#'

            +cast(TT.USER_STATUS as VARCHAR(100)) = 

            cast(ST.USERNAME as VARCHAR(100))+'#$----$#'

            +cast(ST.PROGRAM as VARCHAR(100))+'#$----$#'

            +cast(ST.USER_STATUS as VARCHAR(100))

    )
    ORDER BY USERNAME,PROGRAM,USER_STATUS;
  SET @rerord_count = @@ROWCOUNT;
  COMMIT TRANSACTION;
END
