I can start up Minecraft fine, nothing wrong with that. but when i start up a world, and while playing i click on the taskbar-symbol at the bottom of my laptop's screen to minimize, then click it again to re-open the game, it instantly crashes and i get brought to the launcher displaying an errorcode... 2020-12-17 (1).png shows what i see when the launcher re-opens (The text is in Dutch, but it's saying 'An unexpected error occured and the game crashed. Our apologies for the inconvenience. Closingcode 0').

Also, i don't know if this is off-topic or if this has to do anything with it (probably not because sometimes Minecraft crashes without my screen glitching like on 2020-12-17.png) but this is what i had happen before i had to make my game crash on purpose to be able to do anything again (in-game nothing worked, game completely froze)...

Expected this bug to be fixed with the new mini-update (had to install some data, like 46MB yesterday) but since it isn't i thought 'Why not address it. Haven't checked if someone already reported this bug.
