I have to sign back into my Microsoft account each time I open the game

About once day when I boot up minecraft for the first time, I have to re-sign in to my Microsoft account. I usually have to do this a few times in order for it to work, having to restart the game and trying again about 3 times before it signs me in. Even after it successfully signs me in, after the popup confirming succession with the "Let's Play" button is clicked, the game will crash when it reaches the pan of the nether, where I'll have to restart the game yet another time.
