Seems like the crash is caused by this line: https://github.com/MCCTeam/Minecraft-Console-Client/blob/708815fe616ac99517261045aad21e4749865e9e/MinecraftClient/Protocol/MicrosoftAuthentication.cs#L72

Ensure the key is exist before retrieving it should prevent it from crashing.

I can confirm however mine isn't a crash, it just doesn't want to authentificate. Sometimes it works sometimes not

This happens when your ip is either blocked or rate limited by Microsoft. Try using a proxy.
