The issue is reproducible.
Probable Fixes:
1 -> Switch to earlier version for multi-row insert (using select-union combination) till the issue is being resolved.
2-> Migrate to ExecuteMany() instead of Execute() for multi-row insert. When the number of bind variables are higher ExecuteMany() will be performing much better. So yet another reason for migration.
3-> Migrate from NVARCHAR2 to VARCHAR2 as it also resolves the issue with multi-row insert.
