if plugin is disabled, then everything is fine.
Any workaround?

Do you have sqlite plugin installed? It is required by the plugin.

Thanks, I was using the old version without it, now I understood this is because of the dependency.

Yes, the new version of approve needs sqlite to provide some new features. Please install it and everything should work fine. Please also look at approves documentation since several new things was introduced since previous versions.
