I also have the same issue, even though this issue is a bit old. It appears to happen when there are any other that can be activated ( doesn't have to be active, just has to be anything that expects text input ). When you try to type in the launcher, the text input activates OTHER textboxes from OTHER applications that are NOT in focus. I've only seen this happen in the minecraft launcher, and prevents me from typing anything when some applications, such as discord, are open.
Logging out and logging back in fixes the issue as there are no longer anything that expects text in the background.
