The issue seems to be back.
in 1.21.8 input the command: /give @p minecraft:player_head[minecraft:profile="skipthetutorial"] in a command block and power it.
in 25w34b type: /fetchprofile name skipthetutorial in chat and then click ‘Give Item’ when prompted to to get the player head.
This happens often. Sometimes the player skin loads, sometimes it doesn’t. I really wish I knew why. It only applies to this player skin from what I’ve seen. Maybe it happens to other skins with longer names.
The issue seems to have resolved itself. Maybe the player skin servers caught up. You can mark this as resolved. Although it could pop up again for someone else, so don’t mark that issue as a duplicate of this one please.
It happens in this log. It doesn’t say the command block gave me the head for some reason though.
