Details of the scenario you tried and the problem that is occurring

when changing any config on the tenant, i export the config using:
Export-M365DSCConfiguration -ApplicationId 0791df04-ee1a-4931-9995-XXXXX -TenantId XXXX.onmicrosoft.com -CertificateThumbprint XXXXXXXXXXXXXXXXXXX -Workloads @("intune") -Path C:\t1\july2023
change the av and profile config values:
Export-M365DSCConfiguration -ApplicationId 0791df04-ee1a-4931-9995-XXXXX -TenantId XXXX.onmicrosoft.com -CertificateThumbprint XXXXXXXXXXXXXXXXXXX -Workloads @("intune") -Path C:\t1\july2023\changed

Were you able to verify the content of both configurations? Any chance that one of the configuration does not have any content?

M365TenantConfig_changed.zip
M365TenantConfig_first.zip
Please see both files, it's a test environment so no sensitive information is included. thanks

You can run the New-M365DSCReportFromConfiguration -Type 'HTML' -ConfigurationPath 'C:\T1\july2023\M365TenantConfig_first.ps1' -OutputPath 'C:\reports\M365Report_july2023_inital.html'' and can see the config not sure if it's limted to the New-M365DSCDeltaReport module?

Have you managed to compare the attached reports and replicate the same error? Thanks
