After upgrading a database from Oracle 10g to 18.104.22.168, all Materialized Views (MViews) show a status of COMPILATION_ERROR (in the DBA_MVIEWS view).
The status shown in the DBA_OBJECTS view is INVALID.
However, the Materialized View itself is fine and the data can be refreshed without issues.
Re-creating the Materialized View resets the status to VALID, but this is a very time-consuming operation.
