GCAM aborting when running policy target scenario

[aa9ws]

I'm a new GCAM user. -- Seeking to familiarize myself with the policy target finder functionality. --- Have downloaded model to Windows 11 PC and successfully run the reference case scenario.
When I attempt to run a scenario with the policy target finder turned on in the config file and referencing one of the policy-finder sample files included in the Git download, all GCAM input files load and the following read-out appears in the Command Prompt window (and Main log)

Reading advanced target finder configuration file ../input/policy/forcing_target_2p6_overshoot_test.xml
Policy Target Runner: scenario dispatch #0

Starting a model run. Running all periods.
Model run beginning.
Period 0: 1975

Then the run aborts, all readout from the run is erased from the Command Prompt window and window returns to the original command prompt.
The target-finder log shows:

Starting new scenario: 2p6_test
Setting up scenario: name=
target type: forcing
tax name: CO2_LTG
target value: 2.6

Solving for the initial target. Performing the baseline run.
Policy Target Runner: scenario dispatch #0

Any input on what I am doing wrong would be greatly appreciated.
