Additional context

Add any other context about the problem here.

• Is there anything special about your app?

Anyhow, the error message indicates that you have changed the type of a property after creating the database. This is not supported. If you are still in development, just delete the database file on your test device. If not, then either

• choose a different name or
• annotate the property with @Property(uid: 0), run the generator, then copy and paste the UID from [Change/reset] to create a new property with the same name and discarding the old data. https://docs.objectbox.io/advanced/data-model-updates#how-to-and-example-1
