Thanks. I'll put DisableRBDB in the Xojo folder.

Just to underline:

- this is not a Catalina issue, this is an issue because of changes in RBDB Interfaces of Xojo 2019.2 beta

Hello Jonathan,

In 9.5.3, we started to add methods of the new Xojo API.
SelectSQL for prepared statements will be added in the nearest versions.

VRBPreparedStatement is a part of Xojo RBDB interface.
If you're not using Valentina RBDB, you can disable it - just put DisableRBDB empty file, without extension, near to Xojo.app file.

You can use the Terminal.app for it:
$ touch "/Applications/Xojo 2019 Release 1.1/DisableRBDB"
