"NO Odata route" error message when trying to delete Intune device compliance policy assignments

Describe the bug

I am trying to delete Intune device compliance policy assignments (Entra groups) from compliance policies in Intune, both in graph explorer and using C# SDK, but I get this error:

"No OData route exists that match template ~/singleton/navigation/key/navigation/key with http verb DELETE for request /DeviceConfiguration_2311/StatelessDeviceConfigurationFEService/deviceManagement/deviceCompliancePolicies('{5ea2aa68-e1aa-4dd7-b9aa-779e3a3f9d87}')/assignments('{5ea2aa68-e1aa-4dd7-b9aa-779e3a3f9d87_6f32bcce-4c71-4ef4-b80c-1a08974a7eb3}').",

5ea2aa68-e1aa-4dd7-b9aa-779e3a3f9d87 is my compliance policy

5ea2aa68-e1aa-4dd7-b9aa-779e3a3f9d87_6f32bcce-4c71-4ef4-b80c-1a08974a7eb3 is the assignment ID, which includes the above mentioned policy, as well as my Entra group (6f32bcce-4c71-4ef4-b80c-1a08974a7eb3).

To Reproduce
Steps to reproduce the behavior:

1. Use this format in graph explorer

https://graph.microsoft.com/beta/deviceManagement/deviceCompliancePolicies/{5ea2aa68-e1aa-4dd7-b9aa-779e3a3f9d87}/assignments/{5ea2aa68-e1aa-4dd7-b9aa-779e3a3f9d87_6f32bcce-4c71-4ef4-b80c-1a08974a7eb3}

Would need to replace the ID's.

In C#:

await graphClient.Result.DeviceManagement.DeviceCompliancePolicies[policyID].Assignments[assignment.Id].DeleteAsync();

Expected behavior

According to the documentation this should work, but I am not experiencing that.

Additional context
Add any other context about the problem here.

Start by reproducing the DELETE request in Graph Explorer and with the C# SDK call shown in the issue, using the documented deviceCompliancePolicies/{policyID}/assignments/{assignmentID} endpoint. Compare the returned OData route error with the linked Microsoft Graph deletion documentation; done means establishing whether the documented operation works or identifying the API behavior that must be corrected. No repository file or test is mentioned.
