With a freshly started Minecraft, I most time needs to open a world two times before I'm allowed to enter my local world.

I've captured a video showing this behaviour, but it was a little too large for the bug report, so here is the link to a private video showing this: https://youtu.be/_EnwYUkfWDQ

It shows how I start Minecraft, wait for the login to the Nintendo and Microsoft Accounts to happen, and then how I need to open the world two times before I'm allowed into the world to start playing.
