Top-level exits when given a certain command #2425

Using the following command causes scryer to print to screen (as expected), but then immediately exits back to the command line without an error.

$ scryer-prolog plc01.pl
?- json(J), flowmeter_json(J, Flowmeter), write(Flowmeter), halt.

The plc01.pl file that I start prolog with can be found here: https://raw.githubusercontent.com/stevemolloy/prolog_mps/main/plc01.pl
