The error is that there is no C:datadb, but my dbpath already points to other files in the configuration file

No response is usually normal. Your log has been output to f:mongodblogmongo.log. Any response is also output to this, so just look for any abnormalities.
As for the current process, Windows does not support fork to run backstage like Linux. Of course, it can only be stuck here, and it cannot be turned off. The service is closed.
Another option is to install and run as a windows service so that there will not be an annoying command line stuck all the time. See documentHere.
