This is more of an issue than a bug, but IDK where im supposed to put this. My world is not the issue, but it highlights an issue.

When starting up minecraft, i opened the launcher like normal, and pressed play. I, as the user, should assume it would start up the last thing I had opened. Only to figure out after I pressed play that it had changed my saved presets and opened a preset launcher that i didnt make to join my singleplayer survival in 1.20.1. This process had no way to be stopped (if it does it is not apparent) and automatically opened my 1.20.6 survival world in 1.20.1, clearing my inventory and all my chests, without making a backup.

There was no way for me to have it not open the world, I did not make the preset launcher profile, I could not stop it once started, it did not make a backup (which minecraft would have advised me to do if i tried to do this manually) and this preset was not even in my recently played.
This is a MAJOR design flaw and i am lucky I have a save from earlier today, but many will not be. Why does this exist? It should be reworked or fixed.

If there is a more correct place for me to put this, send me the link, as I do not know where it goes.
