I pasted this command in a command block and got the item, when it immediately crashed. I couldn't even access the world until I cleared my inventory with an nbt editor and downgraded the version to 17w50a. In 50a, this issue didn't happen. When I went back to 01a, I tried out other custom heads which I had been saving in my toolbars. There was no problem when I held these items.
