How has this issue affected you? What are you trying to accomplish?

Sometimes it is unable to open code sandbox

To Reproduce

I'm not really sure what problem, but sometimes this issue might happen for me

Link to sandbox: link (optional)

Your Environment

The report centers on GraphQL CreateVM scheduling and the agent's initialize dependencies operation; start by collecting a reproducible sandbox case and the missing environment details. Trace the failure across those named operations, then confirm that a microVM can open reliably without the cross-device-link error.
