Spawn Bug

So today I went to go play on my survival world and I was ready to beat the game and got really good loot on me which I collected throughout my gameplay. I left the game while inside the nether to go do something in real life so I came back to play and I was where I left off in the nether so I wanted to go back to the overworld and went through the portal but I just got stuck on the generating world, building terrain screen for a good 5 minutes even though the music was playing, so I quit the application and went back into my world, then when I loaded in I got spawned like well over 100 blocks away deep in an ocean with only 3 hearts left and no oxygen and then I drowned and lost everything I had in my inventory which I spent literally days to collect! This is not where it should have spawned me, when I was last in the overworld I was inside the end portal room not deep below the ocean. You can see in the photos attached, I was supposed to spawn inside the end portal room where the other end of my nether portal was but no the game just randomly spawns me under an ocean with no oxygen and only 3 hearts left and there was nothing I could do to prevent my death! I believe this is a spawning bug and not my fault, the game spawned me in the wrong location instead of where it should have spawned me. Please fix this as I lost all my loot and it wasn’t even my fault!!!!!
