Provider does not autoregister

[vRune4]

Bicep version
Bicep CLI version 0.29.47 (132ade51bc)

Describe the bug
While deploying my bicep project to a fresh subscription:
{"code":"SubscriptionIsNotRegistered","message":"Subscripton 'zzzzzzz-yyyy-yyyy-yyyy-xxxxxxxxxxx' is not registered with the required resource providers, please register with the resource providers Microsoft.App and Microsoft.ContainerService."}

To Reproduce
Steps to reproduce the behavior:

This is the resource that fails.

resource container_app_env 'Microsoft.App/managedEnvironments@2023-05-01' = {
  name: '${env_prefix}-app-env'
  location: location
  properties: {
    vnetConfiguration: {
      internal: false
      infrastructureSubnetId: container_app_subnet_id
    }
  }
}

Full bicep project can be supplied if necessary. (I should try to reproduce this with a small sample project, but I'm running out of subscriptions)

Additional context
The group I'm a member of is the owner of the subscription.
