Dialer won't call but instead closes

Blizz1603

Hello, I have installed GrapheneOS yesterday on my Pixel 5 and discovered that I can't make calls half an hour ago. Whenever I try to call somebody the call-screen opens, almost immediately shows 'call ended' and closes afterwards.
This happens no matter who I try to call, I have tried calling via WiFi, turning roaming on and off and also downloading a non-stock dialer. None of this helped.

Do you have an idea about this? Any help would be appreciated.

Mine is having the same issue but nothing is fixing it. I switched APNS, reset the phone to factory, reset network settings, tried lte only, 3g and pretty much every setting.
