Render Command not working

Before when i used the command it opened a small window where you could see the render being processed and previewed but now it only freezes rhino and only says the rendering time but i cant see it
any help?

Hi @Logitik ,

Does this happen with all files or just one? What are the results of the SystemInfo command run in your Rhino 7? Do you have a small sample file to reproduce this that you can share here?
