Error: Disconnected from qemu:///system due to end of file when deploying a VM State Failure

Could someone help me with this problem? That problem gives me when initializing a VM, I installed the stable version 5.12, I think I have carried out the steps as recommended by the documentation, and I even have communication with the node. I thank you in advance for your prompt response.
