Schematic viewer: cannot configure on windows.
Describe the bug
When configuring the schematic viewer for vhdl (GHDL + Yosys) and adding a path to start the oss-cad-suite environment, the TerosHDL: Global terminal doesn't produce any output, and the schematic viewer doesn't work.
The command used to activate the environment is: C:\oss-cad-suite\start.bat &, which works fine (eg. yosysis found) in a CMD-shell. This command is run, as per the suggestion in the field description above: Extra options passed before to run yowasp-yosys or yosys. Eg: 'conda activate base & ' or 'C:/OSS-CAD-SUITE/oss-cad-suite/start.bat & '. This might be related to starting a background process with &, and the terminal output is piped somewhere else?
When removing said command, output is again produced, but initializing the schematic viewer naturally fails:

Double check it. But I think that GHDL+Yosys doesn't work in Windows with oss-cad-suite. What is the output in the Schematic Viewer?

I see. If it doesn't work in windows, please make a clear comment on this in the settings. The schematic viewer window is always empty.
As I said, when using start.bat &, no output is produced, so we can't see the error of the schematic viewer.
I tested it with environment.bat instead: Either as a "normal" command, or as a background process.
Configuring it as environment.bat (normal command, not as a background process) we get this output when verifying the setup:

From the end of the command we can also see the reason for the issue presented in #759, where many empty files are produced.

It seems that oss-cad-suite doesn't support GHDL plugin for Yosys. Try this: https://github.com/ghdl/ghdl-yosys-plugin?tab=readme-ov-file#pre-built-packages
Even though this isn't supported, these issues (as I see it) are related to not being able to see terminal output when using the recommended command .../start.bat &. This comment needs to be considered changed.
It also seems as the .../environment.bat command works better, where it seems to find "yosys_ghdl". However the command "C:\oss-cad-suite\environment.bat --version" seems strange, so I don't know the validity on that.
