So today I was on a server, not Realms, and when I left and entered my local world, I was simply in the void, I was in the Overworld and in Survival mode.

Please provide reproduction steps and/or upload a video recording of the issue with the debug overlay (F3) enabled and showing the game version and system specs. You can record your screen using:
On Windows, the built-in Snipping Tool app (shift+win+S)
On macOS, the the built-in Screenshot app (shift+cmd+5)
Third-party software such as OBS
It is recommended that you trim, convert and/or reduce the quality of your recording so that it is under 10MB, as this will make the upload much quicker.
Are you able to replicate this issue?
