Unable to activate or change minecraft skin

The error message "Cannot activate skin" pops up every time I try to upload a skin or change my Minecraft skin through the java edition launcher. Additionally, when I try to change my skin through minecraft.net nothing seems to happen at all. I have tried multiple methods; different files, redownloading the launcher, searching my laptop for viruses or applications that may be interrupting my game but nothing seems to work and I cannot find a solution anywhere.
