I've tried to change my skin from the default Steve with no success. I've submitted a ticket and they just told me that they couldn't help me and that I should submit a bug issue here after just telling me to relog the minecraft launcher (after I said I've been trying to fix my skin issue for 2-3 days) and checking if the skins had the right size.

On top of doing that I tried to update my skin on both the microsoft account page and on the launcher itself, tried to switch skins, always verified that the skins had the right 64x64 dimensions, and still nothing.

Almost a week into this and tried to re-install the launcher as well, with no sucess.
