I am attempting to run Scilab from the Jupyter environment.
I am running on Windows 11 and installed Jupyter Lab through pip and the program launches successfully. Using the guides on this page I have setup the Scilab kernel for Jupyter lab and am able to execute Scilab functions from the Jupyter window.
When attempting to plot however, the code connects and then gives no output. When I open the CMD window that is running Jupyter I get the following error message:

The code I am running is intentionally simple to test the plotting functionality
x = linspace(0, 10, 10)
plot(x)
When I navigate to the tmp location called out in the error, _ipy_sci_fig_001 is present but does not have a data type. I was able to open the file in GIMP and the graph has been created so it seems the problem is in the handoff after graphic creation.
How best can I troubleshoot this connection?
