I started a new creative world in 21w40a. Everything with the world were normal until 3 days ago. I had updated the world to 21w42a and everything worked fine. I played on the world for 3 days and then it randomly stopped working. Now I can't open the world. As soon as it finishes loading it immediately crashes. The screen is white like I'm in the air and the hud is there but nothing happens and it crashes. I haven't mixed with anything at all I just randomly can't open my world.

I recently updated to a newer version of java so it might have to do with that. Also there is no crash report in ".minecraft" it only says "crash code 0" in the launcher.

Now I've tried re-create the world to try transferring files. The thing is that I cant even recreate it without the same thing happening. Maybe the seed somehow got removed or corrupted?

Tried creating a new world in the sam version and same thing happened. I also tried to play an old 1.17 world in 1.17 and it crashed aswell but in the loading screen. Then I tried an old 1.8.9 world and it worked fine...
