Hello, I've got an issue with the brand new 1.13 version.

Indeed, when I launch it, once in the menu, the game freezes and crashes, I need to wait for Windows to close the game or for me to press alt + f4.

It sometimes work for 10 minutes or so, but crashes when I press alt + tab to go on Discord for instance, and when I press alt + tab again to go back to MC, it crashes immediately. 

I've seen other reports such as this one, but this time  I don't even have a crash report when this occurs, so I don't know what could be the cause of this.

What's more, this visual bug sometimes appear when I freeze as well :
