Zwift not launching from desktop

Been working perfectly fine until today, will not launch from desktop, uninstalled several times. Even download onto another laptop and still the Zwift app will not launch. I’ve looked at previous issues peeps have logged, I don’t have a prefs.xml file to change. I had no issues yesterday, tuned firewall off and still will not launch just get a blank white box. Any suggestion. Running on windows both 10 intel i7 and AMD Ryzen 7 laptops without success.
