Does the format() work outside of the stored procedure?  In psql, for example:
SELECT format('SELECT COUNT(1) filter (where status =''Undigitized''
                            and reason is null and updated_date between %L
and %L) no_deleted_cards
                     from digi_card where created_date between %L and %L
group by months'
                    ,'2023-06-08','2023-06-30');

I tried it, and it doesn't:
ostgres=# SELECT format('SELECT COUNT(1) filter (where status =''Undigitized''
postgres'#                             and reason is null and updated_date
between %L and %L) no_deleted_cards
postgres'#                      from digi_card where created_date between %L
and %L group by months'
postgres(#                     ,'2023-06-08','2023-06-30');
ERROR:  too few arguments for format()

Because you've got four arguments, and you were only passing two.

This works:
postgres=# SELECT format('SELECT COUNT(1) filter (where status =''Undigitized''
                            and reason is null and updated_date between %L
and %L) no_deleted_cards
                     from digi_card where created_date between %L and %L
group by months'
                    ,'2023-06-08','2023-06-30', '2023-06-08','2023-06-30');
format
-------------------------------------------------------------------------------------------------------------------------
 SELECT COUNT(1) filter (where status ='Undigitized' +
                             and reason is null and updated_date between
'2023-06-08' and '2023-06-30') no_deleted_cards+
                      from digi_card where created_date between
'2023-06-08' and '2023-06-30' group by months
(1 row)
