Sql-server – Query Plan Error

I have an interesting situation. I use SQL2014 Enterprise version with SP1.
The following query results an error message :

The query processor ran out of internal resources and could not
produce a query plan. This is a rare event and only expected for
extremely complex queries or queries that reference a very large
number of tables or partitions. Please simplify the query. If you
believe you have received this message in error, contact Customer
Support Services for more information.

The query runs fine without the insert statement. Also the query runs if I interchange where clause, say the exists statement with [step] = 1 after the exists statement with [step] = 3. Actually the SQL is generated dynamically, so interchanging the order in where clause is not a solution for me. This was working fine in SQL 2008 and SQL 2012.

Any idea/solutions for this issue is recommended and I appreciate for you time and effort.

insert into tblPatientConditions (

                and [step] = 7
                and testname = 'DBPSECOND'
            )
        )

The SQL is generated from a set of rules. There are 14 more dynamic SQL statements generated for identifying certain medical conditions and all those queries work fine. Just this one failed and only for inserting to the table. I also tried SELECT INTO #table FROM and that failed.
