Error on .appv file expand for App Attach

Thanks! I found out that error was shown after expand via Azure Cloud Shell. But using Azure Portal UI I get this error:

{
    "responses": [
        {
            "name": "f9bdfd9e-04a0-4d68-9441-e8cf76f1b015",
            "httpStatusCode": 503,
            "headers": {
                "x-ms-failure-cause": "gateway"
            },
            "content": {
                "error": {
                    "code": "ServerTimeout",
                    "message": "The request timed out. Diagnostic information: timestamp '20250317T134606Z', subscription id '', tracking id '20ad8d5e-7289-4a88-9a3b-14018c25d64d', request correlation id '20ad8d5e-7289-4a88-9a3b-14018c25d64d'."
                }
            },
            "contentLength": 258
        }
    ]
}

Should I follow same advices to find the solution?
