Are you trying to run your script file, “ResearchKGM.lsf”? Then change directory to the location of your script file. And use the script filename with your command.

"C:\Program Files\Lumerical\v221\bin\fdtd-solutions" -nw -trust-script -run ResearchKGM.lsf

You will have to "load" the simulation file on your script and the run the loaded simulation file on the script. Why do you want to run the script in command prompt? You are on a Windows PC. Any reason why you are not running your script from the CAD/GUI script editor window with your simulation file?
