Realms STILL Broken

ON SWITCH. I made a world and played on it for a good amount of time before deciding to upload it to a realm (a service I ignificant amount of time) I couldnt. After doing reading on it I presumed it would be fixed in 1.16.2. So I went 2 weeks without playing because I was waiting for the update to happen so I could put it on a realm for other devices. The update is out, the problem is even worse. Not only can I not upload the world, but my system crashes upon leaving the application.
