Getting this error when we updated to 9.14.1369.0. Previously running on 9.7.805.0.

Oracle Version 19.0.0.0.0

Image of the error happening in VS2019 with query.

The bug with a materialization used within the Let operator of LINQ query in EF6 is fixed in dotConnect for Oracle v9.16: viewtopic.php?f=1&t=53190.
