Hi - For Summer '20 Release, getting the following error for deploying Sharing.settings metadata.  Workaround is to set the sfdx-project.json file to "sourceApiVersion": "49.0" instead of 48.0 but this then introduces some additional errors across other metadata.  Any solution to this or has anyone run across this error? 

Deployment Error: 

Error mdapi/settings/Sharing.settings Sharing Property 'deferGroupMembership' not valid in version 48.0
