For reasons I do not understand, when I try to open Commerce Manager or my site locally, I get an error

There is no rate configured for the shipping method Mediachase.Commerce.Plugins.Shipping.WeightJurisdictionGateway, Mediachase.Commerce.Plugins.Shipping.

Full stack trace:

This error appears to me not for the first time. The last time I updated the database from old backups and it all worked, the site and Commers Manager opened. But the error appeared again. I do not understand why it arises, given the fact that I did not make any changes associated with shipping. Just at some point, everything falls and gives an error.

I am using the latest version of Episerver.
