So, here's the context for how I ran into this issue: I wanted to change skins to a more festive one that I made, but then this happened. To clarify things, it's not due to the XP taskbar nor the the yellow stick figure. Might be due to my Windows 10 version not being 21H1 or 21H2. How I ran into the problem: just by clicking on the "Skins" tab in the new Minecraft launcher on Windows 10 20H2
