Thank you for the reply. Disabling app integration will indeed provide a workaround for the issue since it will turn off the feature that is responsible for excessive 1PasswordSLSNativeMessageHost activity.

Let me know if temporarily disabling app integration helps:

Our developers are still investigating the issue and hopefully we can release a permanent fix soon. 🙂
