Recently I did a 64-bit port for a client.
You can load a copy on my plugin download page.
Updated source code is available for Xojo Inc. to update the official plugin soon. My plugin is build with my plugin build system, so it has MBS in the name and includes libraries for Mac, Windows and Linux including ARM, so you can use it in all projects. If you find a bug related to my 64-bit port, please tell me.
