Hi, made an account just to get help for this since it seems like no one else is having this problem! So sorry if I get anything wrong or I posted this to the wrong place!
Every time I launch Minecraft 1.15, it freezes on the opening menu and says it stopped responding, and eventually crashes. I found a tutorial on how to bypass this-- it crashes because two of the same program open for some reason, and the solution is to close both using the task manager. This lets me play the game now, but every time I go in to play a world, my skin is Alex, despite my dozens of efforts to change it to my own custom skin. The skin I'm trying to change it to is neither Alex nor slim model, but it defaults to this every single time, no matter what I do. I've tried changing it on the Minecraft website and the launcher itself, but nothing works. I'm alright with doing an extra step to open the game, but it's basically unplayable because of the sheer rage I experience every time I start a new world only to see Alex's tiny pale twig of a right hand. I would be so much happier if it defaulted to Steve, let alone displayed the skin I wanted in the first place. A more permanent solution to the first problem would be welcome as well as the skin problem, which is what I'm focusing on right now.
