Cannot interface with simulated DAQmx

[Onering20]

I am simulating a PCIe-6259 "Dev1" (generated long before issue) using

NI Max 2023 Q3

NI-DAQmx 21.3

LabVIEW 2021 SP1

In NI-Max I make DataNeighborhood>NI-DAQmx Tasks>MyVoltageTask an Analog input for  Dev1\ai0:31 and click run I get 

DAQ Assistant Error (Repeats many times)

Error -200324 occurred at DAQ Assistant
Possible Reason(s):
NI-DAQmx is unable to communicate with the device. Make sure the device is present in and accessible to the system, and is not currently being reset.
--------------------

Also hitting the reset, self test, self calibrate in NI-Max do not generate errors

Another trying to make a second device,  behaves differently

This problem shows similarly in LabVIEW :

but I do not find tools > Reset DAQmx data

This post put me in the correct direction 

NI Device Loader (nidevldu) was running, how ever I noticed that my Ni-RIO Server (nirioserver) was stopped and starting it fixed the issue immediately
