We have an unattended UiPath robot running on a Windows VM as per schedule. On one occasion, the VM showed a black screen with only File Explorer visible when logging in. Orchestrator showed no job running at that time. UiPath logs show “Creating user session timed out / Could not start executor,” and Windows logs show explorer.exe crashing. A network outage was reported around the same time. Please advise on root cause and prevention.
this probably is related to your infra.
since its a VM, there are high chances that this is due to latency.
Talk to your IT infra about it because this is something which UiPath cannot handle.
SG.
The error happened because windows could not create a full user session after the network outage, which caused explorer.exe to crash. when the session is broken, the unattended robot cannot start and shows “creating user session timed out / could not start executor.”
prevention: keep network/domain connectivity stable, auto‑restart the robot service or vm after outages, and ensure the windows user profile loads correctly.
