Browser-sync not working anymore

I am mac based (catalina).

I used to be able to connect with this line:
browser-sync start --server --browser “Google Chrome” --files “stylesheets/*.css, *.html”

All was good and running with no issues until I installed Bitdefender antivirus.

Now I get this error in Terminal:
Couldn’t open browser (if you are using BrowserSync in a headless environment, you might want to set the open option to false)

Please help if possible,
Thank you very much!
