Discord Bot Slash Command not appear on Win10

This is a recent Discord bug that’s effecting all apis, including discord.py. In other words, there’s nothing that can be done about it for now. Here’s the message that the discord.py developers have left about it:

There are currently a couple of bug that prevent App (slash) commands from
being registered or only a part of them do or the command registers
but does not work. Or the guild_only/default_permissions
kwargs/decorator was ignored. Started: 6 days ago Mobile clients are
unaffected by this

There is an open forum by discord about this in the developers server
(discord.gg/discord-developers) here:
https://canary.discord.com/channels/613425648685547541/969042921024266240

And issues on the docs repo:

1. https://github.com/discord/discord-api-docs/issues/4859
2. https://github.com/discord/discord-api-docs/issues/4856

Confirmed by Danny here:

(yes, this is important)

Things to check:

1. Check the integration tab for your guild to see if the command is there if, continue else the command didn’t sync.
2. Try restarting discord, altering the permissions in the integration tab and re-syncing (button and code)
