CapacitorException: CapacitorSQLitePlugin: null #688

I have an an ionic / capactiror / Angular app which i'm building for Android devices.

I have used the Sqlite plugin succesfully without encrytion while i was developing it.
Now i'm testing with encryption and i keep running into the issue: CapacitorException: CapacitorSQLitePlugin: null

If i remove the app and then run it from vs code with live reload so i can debug it, it will succesfully build the database and i can use it correctly... If i then close the app and restart the debugging from vscode the plugin always returnes the following error.

CapacitorException: CapacitorSQLitePlugin: null

I have created a basic app with just this plugin and i'm about to start the task of copying over my entire project to this project, but i'm hoping this can be resolved without me doing this.

Everything is upto date - and works the first time the database is built / used...

When i run it through Android Studio in the logcat i get the following

To native (Capacitor plugin): callbackId: 40599979, pluginId: CapacitorSQLite, methodName: isSecretStored
callback: 40599979, pluginId: CapacitorSQLite, methodName: isSecretStored, methodData: {}
