Start with the Update-AzCostManagementExport entry point and the generated CostManagement.Autorest/custom/Update-AzCostManagementExport.ps1 line 375 mentioned in the error. Reproduce the PUT request using the issue's command and debug payload, then inspect how the schedule fields are serialized. Done means updating the export succeeds without the invalid properties.schedule.recurrence member error.
