I was playing on my Hardcore world (in 1.20.1) and had just finished setting up a gravity block duper. I tried entering the end portal to see if it was functioning, and the end was taking a while to load in. What I didn't realize is that the End didn't load in at all, and I fell into the void, losing everything.  When I select the option to spectate the world, everything is gone. I can't see the end island, the overworld, nothing. Really frustrating that this is how I lose everything.
