New launcher can't connected to Minecraft services.

After going back and forth for 47 days with Minecraft Help they directed me here. Essentially, when I log into anything but the new launcher it correctly shows that I own the Java version of the game. When I log into the new launcher it never properly authenticates with your servers and I am unable to play/use it. My bandwidth also inexplicably bottoms out whenever the launcher is open.

I have attached every image I shared with the Minecraft Help team over the course of our 27 email exchange. If you require anything else to resolve this please let me know and I will do my best to provide it.
