Nucleus Plus Rev A keeps shutting off by itself [Investigating]

Hi Wes - there is another chat where people are having the same issue and I have shared a screenshot after outputting the Nucleus HDMI to a monitor. Long story short, if you unplug the Nucleus+ from the power mains and then turn it off after some time, the Nucleus boots up and then shuts down only when you attempt to log in (screenshot attached). Thereafter, each time you try to switch on the Nucleus, it powers off on its own in 45-50 seconds.
