[MC-64296] Error 401: Invalid session ID when trying to start realm

The launcher crashes with the error message Error 401: Invalid session ID when I click on the Realms button on the splashpage. 😞
I've been using my Realm exclusively for a couple of weeks now.
I have three other players invited to my realm.
This is the first time I've had this problem--I don't know what's wrong.
Thanks.
