Do you have Node installed on your system? If you do, try running this program:
const os = require('os');
const nif = os.networkInterfaces();
console.log(JSON.stringify(nif, null, 2));
From the program output, look for the first object with
"family": "IPv4" and
"internal": false. This is the address that Monaca Debugger will use.
I’m guessing that both
169.254.44.238 appear in your output and both are non-internal and IPv4, and that
169.254.44.238 appears first.
(By the way, I figured out this behaviour by looking at the Monaca CLI source code. It looks like this is the function that determines the IP address that Monaca Debugger will use: https://github.com/monaca/monaca-lib/blob/766ace80f1245ad7142d1608ca18f1b4e4cfa658/src/localkit.js#L248)
