On Win 11,I try to run chrome using the --remote-debugging-port with --user-data-dir, and the chrome opens, but when I try to find the port using netsat -an that port doesn't shows up. Currently I am using version: 140.0.7339.81. In the past week, around version 136-137, it worked.
Example:
chrome --remote-debugging-port=8888 --user-data-dir=C:\Users\[USER]\AppData\Local\Google\Chrome_for_Testing\test_user
