Nan with initial value of the feeder impedance

I have a composite load (CMLDBLDGU2) at bus 20 for the IEEE39 network. The value of "feeder resistance =0.04" and the value of "feeder reactance = 0.04". If I run the dynamic simulation with these values, all the output is Nan.

If I change these values, for example, 2, 5, the dynamic simulation is run.

I want to run the network with the true values, (0.04, and 0.04). I have tried to shed load, but it also does not work. Could you help me with that? Thank you.

This is my .dyr file.
