Recreating a deleted Postgres flexible server returns Internal Server Error

When trying to create a Postgres flexible server, a "Conflict" is returned with the error: {"code":"InternalServerError","message":"An unexpected error occured while processing the request. Tracking ID: '87e5916a-efa2-4959-b56e-793a3e81232c'"}

The resource has been created before with the same name and was deleted along with the entire resource group on July 11th. Is there any way of checking deleted Postgres flexible servers and potentially do a purge/force remove?

I have tried to create the server using the Portal, the same error happens. Below is the Bicep-code for the Postgres flexible server - this is part of a larger template and the location is "North Europe".

resource postgresql 'Microsoft.DBforPostgreSQL/flexibleServers@2021-06-01' = {
  name: dbServerName
  location: location
  sku: {
    name: 'Standard_B1ms'
    tier: 'Burstable'
  }
  properties: {
    version: '11'
    administratorLogin: dbAdministratorLogin
    administratorLoginPassword: dbAdministratorLoginPassword
    highAvailability: {
      mode: 'Disabled'
    }
    storage: {
      storageSizeGB: 64
    }
    backup: {
      backupRetentionDays: 7
      geoRedundantBackup: 'Disabled'
    }
  }
}
