Later i discovered that you have to also allow Cura and Curaengine to public networks in the firewall settings and then it also solves the issue

Same issue here. I use Cura 4.4.1. on two w10 laptops. An old one and it works fine, but on a new freshly installed Lenovo Yoga it also freezes on startup schreen. Adding cura.exe and curaengine.exe to the firewall settings diddn't solve the issue. Running cura.exe in W8 compatibility mode solved the issue
