Debug Output/Panic Output

# azurerm_resource_provider_registration.logmon["Microsoft.Compute"] will be updated in-place
  ~ resource "azurerm_resource_provider_registration" "logmon" {
        id   = "/subscriptions/<REDACTED>/providers/Microsoft.Compute"
        name = "Microsoft.Compute"

      - feature {
          - name       = "FastPathForced_uswestcentral" -> null
          - registered = false -> null
        }
    }

Expected Behaviour

The resource provider should not change anything because we never introduced the feature:

      - feature {
          - name       = "FastPathForced_uswestcentral" -> null
          - registered = false -> null
        }

wether via terraform nor via Azure Gui config or something else.

Actual Behaviour

Despite the provider was registered, each run of the tf conf reconfigures the following:

      - feature {
          - name       = "FastPathForced_uswestcentral" -> null
          - registered = false -> null
        }

This results in extremely long runs because the reconfiguring of the Resource providers results in 20-30min runs.

Why is the feature enabled anyway? Our location is switzerlandnorth and we never use the uswestcentral region:

      - feature {
          - name       = "FastPathForced_uswestcentral" -> null
          - registered = false -> null
        }

Steps to Reproduce

Configure subscription resource providers via terraform
Rerun the terraform plan/apply. The feature gets introduced without defining it.

Important Factoids

Region is Switzerlandnorth

FWIW seeing the same behavior today.

TF Version 1.5.1
Provider version 3.91.0

Strongly suspecting something on the MSFT side...

My Cx is seeing same issue and its taking them > 16min without any changes to their code. Is there an active case registered that MSFT team is working on? Interested to get an update on potential fix.
