VM creation keeps failing while deploying AVD in host pool.

Hi Matthias-Braun

I did the deployment many times. This time, i got the below

{
"status": "Failed",
"error": {
"code": "DeploymentFailed",
"message": "At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-deployment-operations for usage details.",
"details": [
{
"code": "Conflict",
"message": "{\r\n \"status\": \"Failed\",\r\n \"error\": {\r\n \"code\": \"ResourceDeploymentFailure\",\r\n \"message\": \"The resource write operation failed to complete successfully, because it reached terminal provisioning state 'Failed'.\",\r\n \"details\": [\r\n {\r\n \"code\": \"VMExtensionProvisioningError\",\r\n \"message\": \"VM has reported a failure when processing extension 'Microsoft.PowerShell.DSC' (publisher 'Microsoft.Powershell' and type 'DSC').
