Minecraft doesn't let me put my skin

Before saying my skin is the wrong size, I tried putting my skin put on my phone and it worked ( I play on my tablet)this never happened before the 1.20 ,Minecraft refuses to accept my skin only on my tablet, I cleaned everything, my cache and my data but Minecraft won't read the skin as a skin ( it pops up the message " this is not a Minecraft skin, silly) please fix this issues.
