Recently i got same issue and it comes when Sitecore is not able to connect with xConnect's Reference data service. This error comes when Sitecore Commerce ExperienceAnalytics Core package tries to install Experience Analytics Segments. As soon as it creates segment items, item:saved event deploys those items into xDB using xConnect Reference Data Service. If service is not available it generates error.

By disabling the processor you can continue XC installation but these segments needs to be deployed in xDB to collect commerce analytics data.

To deploy it after XC installation you can make sure your reference data service is working and configured properly in Sitecore connection strings. You can then deploy segments using Deploy marketing definitions tool from Sitecore Control Panel.
