您似乎正在尝试使用仅支持“TrustedLaunch”安全类型的库映像创建VM。当您尝试创建具有不同安全类型的VM时会出现此错误，即，如果您尝试使用具有“Trusted Launch”安全类型的库映像创建VM，则会出现此错误。
根据MS Doc，如果从专用镜像版本创建VM，您会发现由于管理员用户名和密码问题，不允许使用osProfile。相反，您可以创建安全类型为Standard的VM，然后使用库镜像定义和部署VM。
以下是MS中的trusted_launch_VM列表
从门户网站，如果您要创建具有可信启动安全性的VM，请执行以下步骤-

AzurePortal->VirtualMachines->CreateVirtualMachine->Choose securityType->TrustedLaunchVirtualMachine
