Realms Menu crashes

The Realms menu in Java Edition crashes before I can enter my realm. Once I am in my realm it only stays open for a few minutes and then kicks me out. This has only happened today, the official release date of 1.16. The other menus in Java edition work as they're supposed to. The 'Affects Version/s' tab also doesn't have 1.16 listed so I had to use '1.15 (Java Edition)'
