After upgrade to RAD Studio Tokyo Release 2 I get the below error message. [dcc32 Fatal Error] Unit1.pas(7): F2051 Unit OracleData was compiled with a different version of System.Generics.Collections.TArray.Sort.
Unfortunately RAD Studio 10.2.2 has broken compatibility with several 3rd party components. Embarcadero has stated that it has found the root cause of the problem, and is working on a hotfix.
