BUG: MINECRAFT LAUNCHER JAVA EDITION,

Minecraft Launcher is giving me so much trouble. Sometimes when I start minecraft the computer restarts, then I try to enter again (in minecraft Launcher) and it asked me to replace the profile by creating a new one even though I already have a minecraft profile and in doing so I lost my saves . Then the third time he did not even let me play saying that I did not have the game pass also affecting the xbox app because I entered the app (xbox) and he told me that in my profile there was no game pass I restarted the application and the game pass started working again. I truly hope you can solve these problems. obviously I'm talking about the Java Edition version
