ADE Assembler Message 1921 - When running multiple sweep points

Greetings everyone,

I would like to ask for some help with an issue that I have been facing while running simulations on a single transistor circuit.

The process of creating the circuit and setting up the simulation follows below:

Launch Virtuoso - command: virtuoso&
Virtuoso loads the 45nm PDK library without any errors
Using the Library Manager - Created a new library and two cell views (one schematic and one maestro view)
Created the circuit shown in Picture 1 - The transistor used the default library values for the nmos1v model.
Setup the simulation
1. Simulator: Spectre
2. Variables: vgs= 1V, vds= 0V
3. Chosen Analysis: dc, Save DC Operating Point: Enabled, Sweep Variable: Design Variable: vds, Sweep Range: Start 0, Stop 5, Sweep Type: Automatic. (Picture 2)
Run: The simulation was completed successfully with no errors.
Setup the simulation
1. Using the calculator: operating point sweep (os)
2. Selected the transistor model
3. Selected the following parameters: drain current (id), rout, vearly, lambda (1/vearly) (Picture 3)
Run: The simulation was completed without errors, the graphs looked normal but the value fields were showing "eval err" (Pictures 4 and 5)
By adjusting the variable: vgs= 1 2 3 4 5, and trying to run the simulation as before (dc sweep of vds from 0 - 5 with the additional 5 sweeps of vgs) the simulations get stuck on "pending" until the message in Picture 6 pops up.

Below you will find the pictures I have mentioned in my post to help with recreating the process I followed by the netlist of the circuit.

Additionally, I have run the checkSysConf command and attached the output files from that bellow too.

Thank you in advance for any help on the matter.
