Broken functionality of macOSWiFiConfiguration policies

I'm having trouble accessing macOSWiFiConfiguration policies. They are completely inaccessible via the Intune admin portal (no actual data is displayed) and the Microsoft Graph API. When using Graph (/beta/deviceManagement/deviceConfigurations or with policyId) an InternalServerError is returned mid-response, resulting in a truncated and malformed body. This error indicates that the 'wifiRequirePhysicalMacAddressEnabled' property (type Edm.Boolean, Nullable = False) has a null value stored in the back end. The policy also fails to load in the Intune which I suspect is caused by the same underlying issue.

ERROR DETAILS:

Endpoint: GET https://graph.microsoft.com/beta/deviceManagement/deviceConfigurations/{policy-id}

Error code: InternalServerError

Error message: "The property 'wifiRequirePhysicalMacAddressEnabled[Nullable=False]' of type 'Edm.Boolean' has a null value, which is not allowed."

STEPS TO REPRODUCE:

1. Create a macOSWiFiConfiguration policy in the Intune admin portal. Additional note: front end will attempt to create the policy multiple times (around 20), even though the back end responds with a 201 HTTP code.

2. Try to GET the policy via Graph API (returns InternalServerError with malformed JSON body) or retrieve it using the WebUI (no data is shown).

EXPECTED BEHAVIOR:

The policy should be retrievable via Graph API and visible in the Intune admin portal. The property wifiRequirePhysicalMacAddressEnabled should hold a valid boolean value (true or false).

ACTUAL BEHAVIOR:

Failed to retrieve policy through Graph API and Intune WebUI.

Has anyone else encountered this issue? Does anyone know how can I report this directly to Microsoft? All the options I have found lead me to AI chatbots which unfortunately are not helpful at all.

Thank you.
