Steps to Reproduce

1. Go to settings and initiate Bedrock linking
2. Copy the code, enter it, proceed as normal
3. When it tells you you're ready to go, the Minecraft window will say something went wrong.
4. (bonus) you can't exit the error screen and have to close your game lol

Expected Behavior

I should be logged into Bedrock after it tells me i'm good to go

Can you try if the bedrock login works on ViaProxy

Fixed the issue in MinecraftAuth and ViaBedrock (You will have to wait for a new ViaFabricPlus release or use ViaBedrock directly)
