Port in use error?

[LinuxOnTheDesktop]

Hello!

I wonder whether LiveReload 0.1.3, on SublimeText 3 build 4191 on Windows 10 Pro - 22H2 (2009: 19045) (sic), is responsible for (or at least involved in) the following. On some occasions that I load Sublime - I do not know what makes the difference - I receive a pop-up message about a port being in use. (I am afraid that as yet I have no screenshot of that message.) Sublime's console reveals the following.

I removed LiveReload and, thus far, I have not seen the pop-up error box.
