We have a Power Automate flow run once per hour between 1am to 6am. The flow is:

1. Start the VM

2. Call a desktop flow to run in VM

3. Regardless step 2 success or fail, deallocate the VM

The problem is the flow failed from time to time. It is almost 50% of the flow will be failed.

The error is always "Cannot create new session to execute unattended run" in the 2nd step. There is not co-relationship between each success and fail. It just fail randomly. There is no user login to the VM since the flow is running at the VM.

What could be the problem and how should I troubleshoot it?

Sometimes "Cannot create new session to execute unattended run"

I get that error sometimes because UIFlowService is not running. Check that by opening the VM and in Task Manager -> Services tab and find UIFlowService and see if the status is "Stopped". If it is then Right click and "Start".

I don't get this with other VMs so not sure if it has to do with the PAD version I have on that VM (2.46.163.24194)
So maybe try updating the PAD if it is the same version as I mentioned.
