"Failed to connect to domain socket: Connection refused" Error

Hi, I maintain a cloud drive app which transitioned from SMB based mounting of cloud storage to File Provider. Our users on fresh installs of the app are fine, but users who updated from the SMB app are getting an error. I can see in the File Provider logs that the error is: "Failed to connect to domain socket: Connection refused". I can see in fileproviderctl listproviders that the provider does not load. Can anyone help me understand this error or what parts of the system to flush to reproduce the environment of a fresh install?
