DB's last entity ID 5 is higher than 4 from model

See original GitHub issue

when I install a newer version of my app over an old release version caused this Exception ,how to solve it?

I once deleted the files in the folder objectbox-models and rebuild them when coding the new version. Is this the cause?

If you delete and re-generate the model file you have to delete the database (for example by uninstalling the app). Otherwise ObjectBox has no idea how to map existing data to the new model.
