Session executed "convertToCapped" killed. "show dbs" command does not work

I’m newbie on MongoDB. I have execute below command on Collection it’s size like 500GB. I killed (Ctrl+C) the command because it was taking long time. Now, when I execute “show dbs” command it does not return. I think that the proccess killed by me still ongoing.

How can I kill this command? Or what do you suggest me to rollback?

Thank you.

The command is below;
db.runCommand({“convertToCapped”: “Collection_Name”, size: 100000000000});
