Minecraft badlion skin change error code 500?

Hey when I try to change my skin in badlion, a window appears where I have to answer security questions. Unfortunately, these questions somehow don't load and at the top it says "ERROR: Request failed with status code 500" I bought Minecraft with a Microsoft account

Can anyone help me?

I also had, just start the normal minecraft launcher and upload the skin there.

I have that problem too but instead, I need to get one of the skins from the client instead of putting the skin in the launcher
