Launcher Close and Logs out Mojang account

When I start up Minecraft Java Edition, I hit play and it loads about 30 percent before closing without so much as a error code. I have updated my drivers, restarted, uninstalled and redownloaded, and essentially completed any and all check lists I could to solve this problem. None of them have changed anything. On top of that, my Microsoft account remains logged in, but my Mojang one, where I have my Realm subscription, keeps being removed.
