-Hi, my name is Claudeir, I'm happy to help you!
Lately I've seen users with similar problems, as this is an issue exclusively with Minecraft Luncher and it's probably an issue involving your account, you should go directly to the game's support, as we are only community users and non-employees.

-Feel free to leave your opinion, marking as answered if the answer helped, or leaving more details so that we can continue the service, this is very important to us.
Graciously,
Claudeir
