Everytime I press the "windows" key on my keyboard to go to the desktop, the game crash even on the main menu. The error message is "An unexpected issue occured and the game crashed. We're sorry for the inconvenience." Clicking the "view crash report" button does nothing.
When I go back into the world, it goes back to where I was when it crashed so the world saves.

Going to desktop without closing minecraft is very useful for things like checking a potion recipe. This happens to me since 1.15. It never happened in other versions that i played like 1.14.4.
