You wrote that when you kill a process, Docker (Docker Desktop) shuts down, but I haven’t read the spam post after the spam link (no time for reading spam 
), so I didn’t know what you wrote that to. Now I checked, but please, share the process you see in the process list and also how you create the container. Don’t forget to format your post using code blocks as described here: How to format your forum posts
Docker Desktop doesn’t use that port and even if an extension uses it, I don’t think the whole Docker Desktop would stop. I can’t say more until I see what you killed actually.
