Minecraft 1.20.5 has changed syntax on many commands, so most commands will no longer work without an update.
An update is in progress, you can check compatibility progress here.
The minecraft give command for 1.13 removes block ids completely, it also removes
ids from enchantments and changes the dataTag. The dataTag is now part of the
item argument and some of the structure changes. /give <player> <item> [<count>] /give @p iron_shovel{"display":{"Name":"{\"text\":\"Super Shovel\"}"},"Enchantments":[{"id":"efficiency","lvl":5}]} 1
