Launcher doesn't get keyboard input while game is running

Hi, i digged into Jira but could not find a similar problem. 

When the game is running, the launcher doesn't get focus for keyboard input and every input goes to the "last in focus" window. This happens even if the launcher is focused and foreground.

It affects any text input in the launcher, including the login ones.

Everything goes back to normal when the game stops.

I made a video to reproduce this: https://www.youtube.com/watch?v=ZbZFGrUMUdE

I and some friends are having this issue, we are all using macOS. We experienced this issue even before BigSur update.

Thanks !
