Unable to host a multiplayer game on Nintendo Switch

After updating Minecraft to 1.16.20, when you try to host a multiplayer game on Nintendo Switch, your friends can't join your world. It says "Oops! Your Microsoft account was disconnected. To invite more players, sign in on the Main Menu and restart your world.", despite being signed in on the main menu. However, you can still join your friends! They just can't join you.
