NextDNS not working on Win10

Hi,

So far NextDNS works on every device I use except my win10 PC. Activating the app crashes the internet access. I downloaded YogaDNS and get this error message when I try to set it up using my NextDNS credentials:

[02.01 21:16:45] DnsCrypt log: Get https://dns.nextdns.io/e24e57/DESKTOP-UU12I2D?ct=&dns=yv4BAAABAAAAAAABAAACAAEAACkQAAAAgAAAAA: dial tcp <nil>->199.247.16.158:443: connectex: Der Zugriff auf einen Socket war aufgrund der Zugriffsrechte des Sockets unzulässig.

Basically some access restrictions. How do I fix this? I am logged in as an administrator in Win10.
