I have two machines setup to run Power Automate Desktop unattended flows in machine group. They've been working fine for a year. One of them just stopped working. When it tries to run on the one machine it errors out with the message "Cannot create new session to execute unattended run". That's the entire error message.
I have tried searching by the error message. The most common suggestion seems to be that there is someone else logged into the device, but I'm confident that is not the case. In fact, the confounding part is this same machine works if it is not in the Machine group. If I remove it from the machine group, then run unattended flows on it directly, it works great. It only won't work with the machine group.
I have tried all the basic troubleshooting steps. I have uninstalled and Reinstalled Power Automate Desktop on that device. I have removed and readded it to the machine group. I can't think of what else to test.
I have gone into the machine and exported the logs from power automate desktop, but nothing jumps out at me when I try to skim through them.
