I changed my minecraft mane to "__Frosty1" and now I can't join any online servers. I've waited a few hours now and my minecraft name also hasn't changed.

See MCL-12387.
This issue can be resolved by logging out of the launcher and logging back in.
IDK what is but I can use my alt (which I didn't change the name) perfectly fine.
