Error running 'Tomcat': Address localhost:1099 is already in use
The image above is the problem that I currently face.

I tried to solve it by looking at the postings people posted in the face of a problem similar to mine, but I think it's a different matter from mine.
Once in my situation, there is no 'process using 1099 port'.

enter image description here
There is no return value when I type netstat -aon | find "1099".
I've shut down the whole IntelliJ process and rebooted PC.
I don't seem to use port 1099 at all, but there's an error like that.
