Entered the end, then suddenly fell into the void during load time

So after updating to 1.16.210, i wanted to fight the ender dragon again, bought 4 end crystals, and went to the end portal.
I jumped in, and while it was loading i was hearing the damage sound, after thr loading ended i found myself at the bottom of the void, i couldn't even use my elytra.
I lost all of my netherite gear, elytra, and other things that took me long enough to make. Please fix this, iam trying to mess up the files to get my things back.
